what is the difference between reflection and deflection of light?

Hi Amritha!

Reflection:

When light falls on a surface, the direction of the ray is changed. This change in direction is known as reflection of light. The reflected light travels to the same medium it came from.

Deflection:

In physics, deflection means the event of bouncing back of an object, when it collides with a plane surface. The corpuscular theory of light explains the reflection of light with the help of the deflection of small light particles (corpuscles).

Diffraction:

The phenomenon of bending of light around the corners of an opaque object which obstructs the path of light is called diffraction. Interesting patterns are observed when a monochromatic light is diffracted by a small slit.

Cheers!!
