Question

a light ray strikes a plane mirror at an angle of incidence of 35 degree. what is the angle of reflection? 35 degree 70 degree 55 degree 90 degree which color of visible light has the longest wavelength? green red blue violet the angle of incidence is the angle between * the: incident ray and the reflected ray. reflected ray and the mirror surface. reflected ray and the normal. incident ray and the normal.

Explanation:

1. According to the law of reflection, the angle of incidence is equal to the angle of reflection.
2. In the visible light spectrum, red light has the longest wavelength.
3. By definition, the angle of incidence is the angle between the incident ray and the normal.

Answer:

1. 35 degree
2. Red
3. Incident ray and the normal.
