The angle of incidence does not change. I think you want to know the relationship between the angle of incidence and the angle of transmission. In the case of from air to glas, the transmission angle is smaller than the angle of incidence due to a higher index of refraction of glass than that of air. Look up Snell's Law for better understanding.
What else can I help you with?
What happens to light that moves from glass to air when its angle of incidence is greater than the critical angle?
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
How does the angle of incidence compare with the angle of refraction when light passes obliquely from air to glass?
same problem dude..
When a ray of light passes from air to glass for what angle of incidence the ray will not be deviated?
Angle of incidence has to be 0. This means that the ray has to hit normally on the surface of separation of two media
How does the angle of refraction compare to the angle of incidence measured from the normal when going from air to water?
Angle of refraction will be less compared to the angle of incidence in this case.
A light ray goes from air into acrylic block is the angle of refraction larger or the angle of incidence?
The angle of refraction is larger. BOOBIES

When light passes from air into glass which angle is always bigger?
The angle of incidence is always greater than the angle of refraction. The refractive index of glass is greater than that of air, so the speed of light in air is more than the speed of light in glass. Therefore it slows down and bends towards the normal.
What is the critical angle for glass to air surface?
The critical angle for glass to air surface is approximately 42 degrees. This means that when light travels from glass to air and the angle of incidence exceeds 42 degrees, total internal reflection occurs.

What is the critical angel?
The critical angle is the angle of incidence at which light is refracted along the boundary between two media, such as air and glass, but does not exit the medium. Instead, it is reflected back internally.
What does the angle of incidence always equal?
The angle of incidence always equals the angle of reflection in the law of reflection. This means that the angle at which light strikes a surface is always equal to the angle at which it reflects off that same surface.
How does the angle of refraction compare to the angle of incidence measured from the normal when going from air to water?
Angle of refraction will be less compared to the angle of incidence in this case.
For what angle of incidence the lateral shift produced by glass slab is maximum?
the denominator of the formula includes cosine of angle of refraction. If angle of refraction is 90 degrees then the denominator becomes zero and the lateral shift becomes infinity. Now the Question is when will the angle of refraction be 90 degrees? When light travels from denser medium to rarer medium, incidence is at critical angle then your question is possible. Now, the above argument is for the lateral shift that cannot be determined. When the angle of incidence is at 900, then the numerator becomes 'cos r' which is equal to the denominator. Hence L = t following the formula and this is the maximum measurable lateral shift Hope this satisfies your doubt...
What happens to light rays as it travels from the transparent glass of air?
As light rays travel from air to glass, they will bend towards the normal (an imaginary line perpendicular to the surface) due to the change in the speed of light. This bending is called refraction. Once inside the glass, the light rays may undergo internal reflection or continue to travel through the glass depending on the angle of incidence.
What happens to light when it strikes clear glass?
When light strikes clear glass, most of it is transmitted through the material, allowing you to see through the glass. Some light is also reflected off the surface of the glass. The amount of light that is transmitted versus reflected depends on the angle of incidence and the refractive index of the glass.

The angle of refraction is larger. BOOBIES
