15 degrees from the normal - on the other side.

The angle of incidence would be 90 degrees, so the angle of refraction is 0 degrees, as the light ray does not deviate.

It is reflected at exactly the same angle, but on the other side of the normal at the point of incidence.

By convention angles are measured from the normal to the reflecting surface. The angle of incidence, 35 degrees, is equal to the angle of reflection. In this case 35 degrees. The answer is 35 degrees.

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 will be equal to the angle of incidence, which is 20 degrees in this case.

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 ^

Yes, the principle of optical reversibility holds for both reflection and refraction. This means that the path of light is reversible, so if a light ray can travel from point A to point B, it can also travel back from point B to point A.

It's called the angle of reflection. 38 degrees. The angle between the incident ray and the reflected ray is 19 degrees + 19 degrees = 38 degrees. The angle of incidence and the angle of reflection are measured with respect to the surface normal, or a line drawn perpendicular with the surface the light is reflecting off of.

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.
