Which of the following surfaces has the lowest albedo quizlet?
What surface on Earth has the lowest Albedo? The surface of Earth with the lowest albedo are rainforests.
Which of the following has the highest albedo for visible light )?
Snow, which is white in color, reflects almost all of the colors of the spectrum and thus, has the highest albedo or…
What is the distance between successive wave troughs or equivalently successive wave crests?
The distance between successive crests (or successive troughs) is defined as the wavelength. The time elapsed between the crossings of two successive crests through a given point is the period of the wave.
What is the solar radiation received by the Earth called?
The solar radiation that reaches the Earth's surface without being diffused is called direct beam solar radiation. The sum of the diffuse and direct solar radiation is called global solar radiation.
Which albedo is lowest?
When seen from a distance, the ocean surface has a low albedo, as do most forests, whereas desert areas have some of the highest albedos among landforms. Most land areas are in an albedo range of 0.1 to 0.4. The average albedo of Earth is about 0.3….Terrestrial albedo.
| Surface | Typical albedo |
|---|---|
| Fresh snow | 0.80 |
Which one of the following surfaces has the lowest albedo?
The correct option is A 2-3-4-1. Explanation: Fresh snow has the largest reflection and hence highest albedo, whereas Asphalt has the lowest albedo since it absorbs a maximum amount of solar radiation.

| Which one of the following surfaces has the lowest albedo for visible solar radiation? | black asphalt |
| Which one of the following surfaces has the highest albedo for visible solar radiation? | fresh snow |
What is the high point of the wave called the low point what is that point where the wave is exactly halfway between the high and the low?
The highest surface part of a wave is called the crest, and the lowest part is the trough. The vertical distance between the crest and the trough is the wave height. The horizontal distance between two adjacent crests or troughs is known as the wavelength.
What happens to the wavelength and frequency of the electromagnetic waves as it progresses from left to right?
As you go from left → right, the wavelengths get smaller and the frequencies get higher. This is an inverse relationship between wave size and frequency. (As one goes up, the other goes down.) This is because the speed of ALL EM waves is the speed of light (300,000 km/s).
Why does terrestrial radiation occur mostly at night?
The surface of the earth is heated by the process of terrestrial radiation and this heat is transferred to the atmosphere. This transfer takes place mostly at night. Thus, terrestrial radiation occur mostly at night.
Is solar radiation harmful?
Excessive solar radiation can have harmful effects on human health, especially skin and eyes.
Does high albedo increase temperature?
The lower the albedo, the more radiation from the Sun that gets absorbed by the planet, and temperatures will rise. If the albedo is higher, and the Earth is more reflective, more of the radiation is returned to space, and the planet cools. An example of this albedo effect is the snow temperature feedback.
What is high albedo and low albedo?
Albedo is an expression of the ability of surfaces to reflect sunlight (heat from the sun). Light-coloured surfaces return a large part of the sunrays back to the atmosphere (high albedo). Dark surfaces absorb the rays from the sun (low albedo).
What types of surfaces have a low albedo?
An example of a low albedo material is dirt. Dirt tends to be a dark colour (browns, reds, blacks, etc) and so absorb sunlight. They also are very non-reflective and so don't reflect light well.
Which surface would have the lowest albedo or the highest absorption?
Dark surfaces absorb the rays from the sun (low albedo). Ice- and snow-covered areas have high albedo, and an ice-covered Arctic reflects solar radiation which otherwise would be absorbed by the oceans and cause the Earth's surface to heat up.
Which of the following would likely to have the lowest albedo?
The reflection of sun light is very low at forests. So, the forests have the lowest albedo.
What is the lowest point of wave called?
the trough The lowest part is called the trough. The wave height is the overall vertical change in height between the crest and the trough and distance between two successive crests (or troughs) is the length of the wave or wavelength.
Which shows the lowest point of a wave?
Crest – the highest point in the wave. Trough – the lowest point in the wave.
What happens to the frequency of an electromagnetic wave as the wavelength decreases?
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.
What happens to the frequency of electromagnetic waves as its wavelength becomes shorter?
So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. This means that more cycles can pass by the set point in 1 second.
Why the atmosphere is heated more by terrestrial radiation than by insolation?
The upper layer of the atmosphere retains some heat from the sun's rays as they pass through the atmosphere. The sum of insolation obtained on the surface of the earth is much less than that radiated from the sun because of the small size of the earth and its distance from the sun.
Why the atmosphere is heated more by terrestrial radiation than by insulation?
Answer. Insolation reaches the earth's surface in short waves and heat is radiated from the earth in long waves , Hence energy leaving the earth's surface i.e. terrestrial radiation heats up the atmosphere more than the incoming solar radiation i.e. insolation.
Can humans survive radiation?
Although radiation affects different people in different ways, it is generally believed that humans exposed to about 500 rem of radiation all at once will likely die without medical treatment.
Are solar panels safe?
Electricity from solar panels and transmission to the power grid emits extremely weak electromagnetic fields. Exposure to low-level electromagnetic fields has been studied extensively, and there is no evidence that it is harmful to human health, according to the World Health Organization (WHO).
What causes low albedo?
When air temperatures increase and snow and ice melt, the reflectivity of the Earth's surface decreases and, hence, solar radiation is retained. The increase in net radiation leads to increased temperatures and to more ice sheet decay, further lowering the albedo.
Does Earth have a low albedo?
Because much of the land surface and oceans are dark in color, they have a low albedo. They absorb a large amount of the solar energy that gets to them, reflecting only a small fraction of it. Forests have low albedo, near 0.15. Snow and ice, on the other hand, are very light in color.
What does high and low albedo mean?
The higher the albedo, the more the surface reflects light. Snow and ice have high albedos; a dark rock would have a lower albedo. Vegetation… More, the more the surface reflects light. Snow and ice have high albedos; a dark rock would have a lower albedo.
What term describes the lowest point between two waves?
The high point of a transverse wave is a called the crest, and the low point is called the trough.
What do you do when you are at your lowest point?
Don't stand still and look down at your low point. Put your head up and take small steps forward in the direction you know you must head.
What is the lowest point of transverse wave?
The high point of a transverse wave is a called the crest, and the low point is called the trough.
