Question

Answer in one word.
1. The angle between the incident ray and the normal
2. The colour resulting from mixing two primary colours
3. The image that is obtained on a screen
4. The reflection of light from a smooth surface
5. The return of light after striking a surface​

Answer 1

Answer:

1.The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence. The angle between the reflected ray and the normal is known as the angle of reflection.

2.EX - Purple, Green, and Orange.

3.A real image is always obtained on a screen. Concave mirrors can form both real and virtual images.

4.Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. ... This is called diffuse reflection.

5.reflection: The return of light, heat or sound after striking a surface.
