What is angle of incident if the reflected ray is 90 degree to incident ray?

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.

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.


Why light ray does not change it path when fall prallel to the normal?

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


What is the angle of reflection if the angle between the incident ray and reflected ray is 140 degrees?

The angle of reflection is 140/2 = 70 degrees. The angle of reflection is the same as the the same as the incident.


What is the angle of incidence if the angle of reflection is 15 degrees?

If the ray is incident at right angles to the reflection surface, angle of Incidence will be 90 degrees and so will be the angle of reflection. In such a case, the incident ray, the normal and the reflected ray coincide.


When the incident angle equals the transmitted angle?

Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.Either when they are both 0 degrees (the incident ray is perpendicular to the surface) or the refractive indices of the two media are the same.


Why can the refracted ray can also be the incident ray?

It only happens when the incident ray is shone at 90 degrees. The refracted ray will then travel along the same path as the incident ray. This is known as total internal refraction.
