If the ray hits the mirror at an angle of 30 degrees with the mirror surface, the complementary angle that the ray makes with the normal (perpendicular) to the mirror at the point of incidence is (90 - 30) = 60 degrees and since angle of incidence is equal to angle of reflection in a plane mirror, the angle of reflection is 60 degrees.
yes.
angle of incidence
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.

The angle of incidence is the angle between the incident ray and the normal (perpendicular) to the reflecting surface.

yes.
The angle made by the incident ray with the normal is called the angle of incidence.
A plane mirror is a mirror with a planar reflective surface. For light rays striking a plane mirror, the angle of reflection equals the angle of incidence. The angle of incidence is the angle between the incident ray and the surface normal (an imaginary line perpendicular to the surface). Therefore the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects.
when a ray of light falls normally ie. perpendicular to the refracting or reflecting ,the the angle of incidence is zero(angle of incidence is the angle between the incident ray and the normal at the point of incidence) A ray with 0 angle of incidence doesnot suffer any change on refraction and goes straight into the second medium.
It is the angle between an incident ray and the perpendicular to the surface at the point of incidence.
The ray of incidence is the light ray hitting the mirror plane and the ray bouncing off is the reflection ray. An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence
The angle of incidence it he angle at which the incident ray stikes the plane of the surface.
