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.
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.
When a ray of light from air enters to glass what happens to velocity?
The velocity of light decreases when it enters glass due to its higher optical density compared to air. This causes the light ray to bend towards the normal line at the boundary between air and glass.
In which of the following materials is the velocity of light greatest A Air B Water C Crown glass D Fused quartz?
The velocity of light is greatest in fused quartz. The speed of light varies depending on the medium it travels through, with the highest speed occurring in materials that have low refractive indexes, such as fused quartz.
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 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.
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.

How would the terminal velocity of an object falling towards earth differ than the terminal velocity of the same object falling through water?
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
Why is terminal velocity in water less than the terminal velocity in air?
The incompressibility, inertia and relatively higher viscosity of water make it difficult to displace, so its reactive forces on the falling object are greater; hence the terminal velocity is reduced.
What material has the greatest velocity of light?
air
Compared to air the speed of light in water is?
The speed of light in water is about 25% slower than in air. This is due to water's higher density and refractive index, which causes light to propagate more slowly.

Why does light slow down in air and water?
Light slows down in air and water because these mediums have a higher refractive index than vacuum. The interaction between light and the atoms or molecules in air and water causes the light to be absorbed and re-emitted, resulting in a slower speed for the light waves.
