What is a ray in math?
When viewed as a vector, a ray is a vector from a point to a point . In geometry, a ray is usually taken as a half-infinite line (also known as a half-line) with one of the two points and. taken to be at infinity.
What does ray look like in math?
A ray has a starting point and continues indefinitely in one direction. The starting point of a ray is called the endpoint. A ray does not have a height or width, but it has length. However, the length is not measurable because it goes on forever in one direction.

Pick a point on the top of the object and draw two incident rays traveling towards the mirror. Using a straight edge, accurately draw one ray so that it passes exactly through the focal point on the way to the mirror. Draw the second ray such that it travels exactly parallel to the principal axis.

What is ray diagram?
A ray diagram is a diagram that traces the path that light takes in order for a person to view a point on the image of an object. On the diagram, rays (lines with arrows) are drawn for the incident ray and the reflected ray.
How do you draw a ray diagram step by step?
Step-by-Step Method for Drawing Ray Diagrams
- Pick a point on the top of the object and draw two incident rays traveling towards the mirror. …
- Once these incident rays strike the mirror, reflect them according to the two rules of reflection for concave mirrors. …
- Mark the image of the top of the object.
Why do we draw ray diagrams?
A ray diagram is a representation of the possible paths light can take to get from one place to another. This is often from a source or object to an observer or screen.

What is a ray for Class 6?
Hint: Ray is an example of line that covers all the distances from its starting point in a straight path in any direction. So, we can say that a ray is an example of a line or a segment of line. Since, a line does not have any direction but it has two points with start and end.

What is ray draw any ray?
What is a Ray? In geometry, a ray can be defined as a part of a line that has a fixed starting point but no end point. It can extend infinitely in one direction. On its way to infinity, a ray may pass through more than one point. When naming a ray, it is denoted by drawing a small ray on top of the name of the ray.
