angle of incidence is equal to angle of reflection.
30 degrees as the angle of reflection is equal to the angle of incidence
the angle of reflection is the angle where light bounces off the object. for example if you have a mirror the angle of reflection is the one that you can point a laser at the mirror and bounces off.
No, if the mirror is flat (a plane), the angle of incidence always equals the angle of reflection.
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.
This is the second law of reflection phenomenon. So if a ray falls normally on the reflecting mirror then the angle of incidence will be 0. So as the angle of reflection also is to be 0, the ray just retraces its path. That is it is coming back in the same straight line.
If a light ray is reflected from a flat mirror with a reflection angle of 55o then the angle of incidence was also 55o. When reflecting from a mirrored surface, the angle of incidence equals the angle of reflection.
The angle of reflection.
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.
It is equal to the angle of reflection.
they are equal
