Question

Which phenomena can be satisfactorily
explained using ray opties? State the
assumptions on which ray optics is based​

Answer 1

Ray optics.

Explanation:

Using ray diagram, the phenomena of reflection and refraction of light is explained. The bouncing back of light is called reflection while the bending of light when it reaches the boundary is called refraction of light.

Assumptions on which ray optics is based are :

1. The light travels in a straight line as they travel in a homogeneous medium .

2. The light rays bend and sometimes it splits into two paths.

3. The light rays follow curved paths in a medium in which the refractive index changes.
