The incident angle to the Mirror will be 10 deG.
if one is to define this question one will be aware that the normal is perpendicular to the surface and thus creates a angle of 90 degrees.
It is reflected. Depending on the shape of the mirror, this can be at a variety of angles. Assuming the question refers to a flat mirror that is hung on a wall; a plane (flat) mirror has an imaginary straight line at a right-angle to it, called the normal. A ray of light hits the mirror at an angle to the normal, but is reflected at the same angle that it hits the mirror in the opposite direction. So if a ray hits the mirror at 45 degrees from the normal, it will be reflected at 45 degrees from the normal in the opposite direction.
Light hitting a flat mirror at an angle is reflected at the same angle, relative to the mirror surface.
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
30 degrees
The angle between the incident ray and the mirror is equal to the angle between the reflected ray and the mirror.
The angle of incident is 45 degrees. The incident and reflected ray have the same magnitude and if the sum of the magnitudes is 90 degrees the incident is 45 degrees.
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 ^

A line of reflection is a reflected line, often off of a mirror. If a flashlight sends a beam of light at a mirror (the light is called the incident beam), the angle at which it hits the mirror will equall the angle at which the reflected beam of light (called the reflected beam), exits the mirror. This is called the Law of Reflection. This is why light is reflected from a mirror at the same angle at which light struck its surface.

Call the angle from the incident ray to the normal X. The angle of the reflected ray to the normal also has to be X because the incidence angle and the reflected angle are equal by law of reflection. Since the angle between the reflected and incident ray is 90 degrees: 2*X = 90 So, X = 45 degrees.
The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.
To rotate a mirror so that a reflected ray rotates through 25 degrees, the mirror should be rotated half that angle, which is 12.5 degrees.
The angle of incidence is also 55 degrees because it is reflected
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.
It is 0 degrees.
15 degrees from the normal - on the other side.
