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.


What is the velocity of light in air and water?

The velocity of light in air is about 299,792 kilometers per second, while in water it is about 225,000 kilometers per second. This difference is due to the differing refractive indexes of air and water, which affects the speed at which light travels through these mediums.


Is the velocity of light higher in water or in air?

The velocity of light is higher in air than in water. In a vacuum, light travels at its maximum speed of approximately 299,792 kilometers per second, which decreases when it passes through a medium like air or water due to interactions with the medium's atoms and molecules.


How we can calculate the velocity of light in water?

The following assumes you already know the speed of light in a vacuum. You can do measurements related to refraction, applying Snell's law to the angles you measure. This gives you the index of refraction.Once you know the index of refraction, you divide the speed of light in the vacuum by the index of refraction, to obtain the speed of light in water.


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.

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.

How does refraction occur in water?

It is because of the change in velocity of light in two different media.

What is the velocity of light in meters?

the velocity of light is 300000000 m/s


What happens when light passes through something?

The velocity of light is greatest when travelling through a vacuum. When travelling through something else, a glass material say, then its velocity is slower. The refractive index is the ratio of the speed of light in a vacuum to the speed of light in that substance. For example light travels in a vacuum about 1.3 times as fast as in water, so we say water has a refractive index of 1.3. And it is likely that the velocity in the glass will be different at different wavelengths of light.


What is the average velocity of light?

There is no average velocity of light. Within a given medium, the velocity of light is fixed and absolute. In a vacuum, it is approximately 3.0 x 108 m/s, or 186,000 miles per second. It would be somewhat slower through denser media like water and glass.

What would be the velocity of ball which is thrown by the man who running at the speed equal to the velocity of light?

As velocity never exceeds the velocity of light.... so i hope a man running with the velocity of light will not be able to throw a ball with any velocity.......... we may get the maximum n minimum velocity with which that can be thrown mathematically that we may get it to be zero................
