The critical angle is not the same thing as the angle of incidence.
There is a reason the confusion. The critical angle is defined as the smallest angle of incidence which results in total internal reflection.
Every plane wave incident on a flat surface has an angle of incidence. That can be any angle. When a wave travels from a dense medium to a less dense medium, there comes an angle of incidence where there is no transmission into the less dense medium. We say then that for an angle of incidence above the "critical angle" the result is total internal reflection.
It is also true that with Snell's law, the critical angle is the particular angle of incidence which would result in a 90 degree angle of refraction.
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
For a smooth surface, the angle of incidence is the same as the angle of reflection.
Yes.
The angle of incidence is the angle of which it item is reflected, this leads us on to the fact that the angle of incidence will always be the same as the angle of reflection.
None. They are the same angle.
Angle of Incidence = Angle of ReflectionThis is only true if the angle of incidence is greaterthan the critical angle.
Angle of incidence can be anything. Angle of reflection is the same as angle of incidence.

Yes.

no
yes it is
The Critical angle of perspex is 42o.It is the same as the critical angle of glass.
1. The angle of incidence is equal to the angle of reflection. 2. The reflected ray, the incident ray and the normal at the point of incidence lie on the same plane.
The angle of incidence and the angle of reflection are related in the sense that the two angles are always the same. They are always equal.
The angle of incidence is defined as the angle between the incoming light and the line that is normal to the surface at the point where the light 'hits' the surface. The reflectrion angle is the same as the incidence angle. If the angle between the incident ray and the mirror ray is 50, then the angle of incidence is half of this. That is, 25 degrees.
None. They are the same angle.
