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 incidence compare with the angle of refraction when light passes obliquely from air to glass?
same problem dude..
What happens to the angle of incidence from air to glass?
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.
Which angle hits a mirror or glass block?
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.
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.
What is a piece of glass that has apolished flat sides at an angle?
A bevelled piece of glass.

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.

If Light goes from flint glass into ethanol The angle of refraction in the ethanol is 27.6 What is the angle of incidence in the glass?
If light goes from flint glass into ethanol and the angle of refraction in the ethanol is 27.6, the angle of incidence in the glass is approximately 23.21. This calculation is based on refractive index of pure flint glass being 1.60 and refractive index of ethanol being 1.361.

Describe an experiment to find the refractive index of a glass block?
You can investigate fraction in glass using a rectangular glass block. By tracing the rays of light on a piece of paper, you can measure the angles of incidence (i) and refraction (r). If you repeat this process for a range of different angles of incidence, you would find that the sine of the angle of incidence and the sine of the angle of refraction are constant. This ratio is called the refractive index of the material, and is given the letter n.The angles of incidence and refraction are related by the following equation:sin in=__________sin r
What does the law reflection say?
the angle of the ray of reflection is equal to the angle of the ray of incidence, in other word if a light wave hits glass at an angle of 30 degrees, the angle of reflection will also be 30 degrees
How is the refracting angle related to grazing incidence and grazing emergence?
Grazing emergence occurs when the incident ray is makes an angle between itself and the normal which is equal to the critical angle (42 for glass).
Why does the light ray bend as it passes from the air to glass or from glass to air?
When light travels, it goes through a substance called a medium which could be anything such as air, water, or glass. Different mediums have different contents within themselves, such as its density, thus giving themselves different "Angles of Incidences". As it passes from one medium to another, the light ray's speed and wavelength are changed, so it'll either travel faster or slower than the previous speed of light. The angle will be given to the ray based on the medium's Angle of Incidence as mentioned before.
How angle of incidence affect refractive index of a material?
The angle of refraction is the angle between the refracted ray and the normal (a perpindicular line to the tangent and the plane of the surface). A ray that enters at the normal angle leaves at the normal angle; there is no angle between the ray and the normal, so it is 0o.
What happened when a ray of light is shone at a glass block?
It all depends on the angle if incidence. In general the light will refract i.e. bend through the glass and come out at the other end. Also, the speed of light will vary through the glass.
