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.

What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?
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.
What is the advantage of measuring the angle of reflection and angle incident on either side of the normal to the surface of the mirror?
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.
How do you find the angle of reflection off of a mirror?
The angle of reflection (θr) off a planar surface (eg. mirror) is equal to the angle of incidence (θi) on that surface. They are measured with respect to the normal, which is an imaginary line drawn perpendicular to the surface. Or, in simpler terms, the angle of reflection is the same as the angle of incidence.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?
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.
A ray of light strikes a plane mirror such that angle with the mirror is 30 degreewhat is the angle of reflection?
30 degrees as the angle of reflection is equal to the angle of incidence
What angle is the same distance from the normal on a plane mirror as the incident angle?
The angle of reflection.
Light strikes a mirror at 20 degrees to the normal what will the angle of reflection be?
The reflection angle will also be 20 degrees from the normal on the other side of the normal in the same plane.
What is plan mirror?
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.
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 30 degrees with the mirror surface?
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.
What are value of angle of incidence and angle of reflection for normal incidence of light on mirror?
Both are zero. Thereby it obeys the second law of reflection ie angle of incidence is equal to angle of reflection.
What is the advantage of measuring the angle of reflection and angle incident on either side of the normal to the surface of the mirror?
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.

A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surfaceWhat will be the angle of reflection?
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 ^
What will be the angle of reflection if a ray of light is incident towards a plane mirror at an angle of 45 degrees with the mirror surface?
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.
What is the angle between the normal and the surface of a mirror?
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.
