What image is formed in water?
The image formed in water is erect and virtual. – The reflection of an object into water is its water image. – It appears by inverting an object upside-down ie vertically. – The water image is formed on the surface of still water. – Virtual images can be seen through objects like mirrors/water.
Is an image in water real or virtual?
Light rays reflected from the fish are refracted at the surface of the water, but the eyes and brain trace the light rays back into the water as thought they had not refracted, but traveled away from the fish in a straight line. This effect creates a "virtual" image of the fish that appears at a shallower depth.
Which of the following is a true statement about virtual images?
Which of the following is a true statement about virtual images? A virtual image is formed at the position from which the rays appear to have originated. If an object is placed a great distance away from and in front of a converging lens such as the one shown in the video, where will its image be formed?
Why do we see our image in water?
Answer. We can see our images in the water of swimming pool because water is transparent in nature andthus, reflect much of the light fallen on it. It also reflects the image that is seen on it, just like a mirror, due to which we can see ourselves very clearly when we look into the water from the poolside.
What’s the meaning of erect image?
An erect image, in optics, is one that appears right-side up. An erect image is formed when both of the rays intersect each other's a certain point then an erect image is formed It is an image in which directions are the same as those in the object, in contrast to an inverted image.
What type of image is seen when we view an underwater object?
Q10 When we view an underwater object, is the image we see the real image or a virtual image? The image must be virtual since the rays do not travel through the spot where the image is formed.
How virtual image is formed?
A virtual image is produced with the help of a diverging lens or a convex mirror. A virtual image is found by tracing real rays that emerge from an optical device backwards to perceived or apparent origins of ray divergences. Because the rays never really converge, a virtual image cannot be projected onto a screen.
Is your image erect or inverted it is real or virtual?
Virtual and Real images
| Real Image | Virtual Image |
|---|---|
| Real image can be seen on the screen. | Virtual images cannot be formed on the screen. |
| It is always inverted | It is always erect. |
| It is formed when ray of light after reflection.refraction meet at some point | It is formed when ray of light appear to meet at a point. |
Is the image inverted or upright?
When the image is on the same side of the mirror as the object and the image distance is positive then the image is said to be real and inverted. When the image of the object is behind the mirror and the image distance is negative, the image is said to be virtual and upright. Was this answer helpful?

Does water refract or reflect light?
Water and glass not only reflect but also refract light. This means that as a light beam enters water or glass, the light bends.
What is erect image and inverted image?
If the image formed is upside down w.r.t the object , it is said to be inverted. Real images are always inverted. If the image is upright (not upside down) w.r.t. the object, it is said to be erect. Virtual images are always erect.
What is real and inverted image?
A real image occurs where rays converge, whereas a virtual image occurs where rays only appear to diverge. Real images can be produced by concave mirrors and converging lenses, only if the object is placed further away from the mirror/lens than the focal point, and this real image is inverted.
How do objects look when they are submerged in water?
Looking from above, an object under water appears larger than it does in air. It's not that the image the light gave our eyes is bigger. It's that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water's surface.
What is erect and inverted image?
If the image formed is upside down w.r.t the object , it is said to be inverted. Real images are always inverted. If the image is upright (not upside down) w.r.t. the object, it is said to be erect. Virtual images are always erect.
How erect image is formed?
In optics, an erect image is one that appears right-side up. An image is formed when rays from a point on the original object meet again after passing through an optical system. In an erect image, directions are the same as those in the object, in contrast to an inverted image.
What is the focal length of convex mirror positive or negative?
both convex mirror and convex lens have negative focal length.
What is an inverted image?
Inverted image means the image is upside down compared to the object. The real images formed by the concave mirrors are inverted. The rays from the top edge of the object are reflected downwards below the principal axis by the concave mirror. Similarly, the rays from the lower edge of the mirror are reflected upwards.
Why do images reflect in water?
The most fundamental answer is that water reflects light because the wave impedance of water is different than the one of air and the electric and magnetic field must be continuous everywhere in space.
What is water image and mirror image?
The water image is the inverted image obtained by turning the object upside down. The top and bottom part of the image will be changed, while the left and right-hand side of the image remains the same. In the Mirror image left side and right side changed vice-versa where top and bottom remain the same.
What happens to light in water?
When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it 'bends' more towards the normal line.
What is inverted and lateral image inverted?
Answer: Laterally inverted means the left and right sides of the image are interchanged. Inverted means the image is upside down. A mirror forms a laterally inverted image, which cannot be caught on a screen because it is virtual. A virtual image is always erect.
What is meant by upright image?
When the image is on the same side of the mirror as the object and the image distance is positive then the image is said to be real and inverted. When the image of the object is behind the mirror and the image distance is negative, the image is said to be virtual and upright.
When real image is formed?
Real image formed when the rays of light after reflection or refraction actually converge at some point and when objects are placed outside the focal length of a converging lens or outside the focal length of a converging mirror.
Why do objects look different in water?
An object seen in the water will usually appear to be at a different depth than it actually is, due to the refraction of light rays as they travel from the water into the air.
Why does an object look bigger in water?
Did you see how objects appear larger when looked at through a water drop? The surface of a water drop curves outward to make a dome. This outward, or convex, curvature bends light rays inward. The result is an enlarged image on the retina of your eye.
What means erect image?
An erect image, in optics, is one that appears right-side up. An erect image is formed when both of the rays intersect each other's a certain point then an erect image is formed It is an image in which directions are the same as those in the object, in contrast to an inverted image.
Is the image erect or inverted?
| Difference Between Real Image and Virtual Image | |
|---|---|
| Real Image | Virtual Image |
| Real images are inverted | Virtual images are erect |
| A real image is always formed by a convex lens. | Virtual images can be formed by concave, convex or plane mirrors. |
Why focal length of convex lens is positive and concave is negative?
That means that the focal point is on the same side of the lens as the light rays were coming from. Convex lenses have real focus while concave lenses have virtual focus hence the focal length is positive and negative for convex and concave lenses respectively. ∴ The power of the concave lens is negative.
Why focal length is negative in concave mirror and positive in convex mirror?
The focal length of a concave mirror is negative because the focus of a concave mirror is in front of the mirror, on the left side. Whereas, The focal length of a convex mirror is positive because the focus of a convex mirror is behind the mirror, on the right side.
