The reflection angle will also be 20 degrees from the normal on the other side of the normal in the same plane.
it reflects of the mirror. a very small part of light is absorbed by the mirror a rest of it is reflected back in the same medium . following the 1st law of reflection , a ray of light falling on a mirror is reflected back making an equal with the "Imaginery normal to the point of incidence."
As the incident ray coincides the normal so the incident angle is 0 degree and angle of incident equals to the angle of reflection so the ray after reflection retraces its orignal path. By mohit agarwal
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.
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
Both are zero. Thereby it obeys the second law of reflection ie angle of incidence is equal to 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.
The angle between the normal and the surface of anything is by definition always 90 degrees, regardless of whether it is a mirror, a piece of concrete, a wooden plank, etc.
The law of reflection: When a ray of light reflects off a mirror, the angle of the incidence ray is equal to the angle of the reflection ray. Therefore, an incidence ray of 45 degrees will have a reflection ray of 45 degrees. As both rays are equal, either side of the normal line, then adding both angles equals 45 + 45 = 90 degrees. The normal line is a line perpendicular to the surface of the mirror.
The angle of reflection is equal to the angle of incidence. It will be at 30o to the surface of the mirror (from the opposite edge) ^ This answer is not correct for SURFACE, but is correct for RELATIVE ^
96 degress? If the light ray is straight, and if the mirror isn't bent, then the angle of reflection is exactly 48 degrees, the same number of degrees as the angle of incidence. That's the law of reflection.

The angle of reflection.
As the incident ray coincides the normal so the incident angle is 0 degree and angle of incident equals to the angle of reflection so the ray after reflection retraces its orignal path. By mohit agarwal
Some of it is absorbed. Most of it is reflected according to the normal rules 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.
We measure them on the either side of the mirror and not on the side of the normal to the surface of the mirror because, if the mirror or any reflecting surface is bent, then there will be a difference between the angle of incidence and angle reflection which can be avoided by measuring those angles on the either side of the mirror.
When light bounces off something, it is reflected.
