Is the velocity of light higher in water or in air?
It's greater in air than in water.
What is the velocity change when the ray of light passes from air to glass?
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
Is velocity of light constant?
Yes according to most theories the velocity of light in a vacuum is constant. (In water and glass it is slower!)
When a ray of light from air enters to glass what happens to velocity?
it decreases
In which of the following materials is the velocity of light greatest A Air B Water C Crown glass D Fused quartz?
The answer would be air. The other mediums have higher indices of refraction.
Does the air have the larges velocity of light?
The velocity of light is highest in a vaccum; slightly slower in air, and a LOT slower in water.

What happens to the velocity and wavelength of light when it passes from air into water?
The speed of the light decreases, and its wavelength increases by the same factor.
What material has the greatest velocity of light?
air
Is terminal velocity the same in water as in air?
no
Explain why refractive index values of liquids are greater than one?
The velocity of light in a liquid sample is always less than the light in air The velocity of light in a liquid sample is always less than the light in air

The answer would be air. The other mediums have higher indices of refraction.
Which factors affect the velocity of light?
The speed of light in a vacuum is constant. Otherwise, the speed of light will depend on what materials it travels through. For example, the speed of light in air is similar to the speed of light in a vacuum; in water, it is quite a bit slower.
What is the relationship between the frequency and wavelength of a water wave?
The relationship v = T * λ (speed = frequency * wavelength) is true for all waves. For anything with a constant speed, higher frequency means shorter wavelength.
