Angle of incidence has to be 0. This means that the ray has to hit normally on the surface of separation of two media
same problem dude..
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.
The angle does not hit anything! A ray of light hits a mirror or glass block and the angle that the ray makes with the vertical at the point of contact is the angle of incidence.
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.

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.

Violet light is deviated the most when white light falls on a glass prism due to its shorter wavelength compared to other colors in the visible spectrum. This causes it to refract more as it passes through the prism, resulting in a larger angle of deviation.
Light can both go through and reflect off of glass. When light passes through glass, it is transmitting through the material. However, if the angle of incidence is steep, light can reflect off the surface of the glass.

The refractive index of a glass slab can be determined by measuring the angle of incidence and the angle of refraction as light passes through the slab. By using Snell's Law (n1sin(θ1) = n2sin(θ2)), where n1 is the refractive index of the medium before the glass slab, θ1 is the angle of incidence, n2 is the refractive index of the glass slab, and θ2 is the angle of refraction, the refractive index of the glass slab can be calculated.
It does not move from glass to air but undergoes internal refraction. That is, it is refracted back into the glass at the interface.
The lateral displacement (D) of an incident ray passing through a glass slab can be calculated using the formula D = t * sin(i - r), where t is the thickness of the glass slab, i is the angle of incidence, and r is the angle of refraction. This formula takes into account the deviation of the ray as it passes through the glass slab.
The lateral shift produced by a glass slab is maximum when the angle of incidence is equal to the critical angle of the glass-air interface. This critical angle is defined as the angle of incidence that produces an angle of refraction of 90 degrees within the glass, resulting in total internal reflection.
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.
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.
