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.

Does a convex mirror refract?
No pure mirror refracts. Refraction is caused by a change of the medium through which the light passes, which is accompanied by change of refractive index (change in the velocity of the light).
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!)
Light refracts when light passes from one?
Some kind of lens or a change in a substance: the surface of a pond, through a prism, through glass... all of these may refract light.
What happens when light passes from three different mediums like water to glass and glass to air?
In that case, it will change direction twice - in this example, once when it changes over from water to glass, and once when it changes from glass to air.
Can all light pass through glass?
All light passes through glass that is transparent. But, if the glass is translucent (such as some bathroom windows or shower doors for privacy), only some light passes through, causing you to not see the object clearly.
What causes the change in direction when light passes into glass?
REFRACTION

Why are glass material transparent?
light passes through glass
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.

When light passes at an angle from air to glass do the light changes direction due to refraction?
yes light changes its direction when it passes form air to glass due to refraction of light coz air has less density n glass is a solid so it has more density due to that when light goes form air to glass then its speed decreases n its always bends towords the normal. but if light will go perpendicularly form air to glass then it will not change its direction.
What will happen when ray of light passes through a glass slab?
speed of light will decreases
When light passes OUT of glass what does it do?
Unless it`s colored glass, it will still shine its original color.
Why does the light bend as it passes from air to glass or from glass to air?
This is due to the difference in optical density.
