Question

why three properties of light?​

Answer 1

Answer:

the three properties of light is speed reflection and colour

Answer 2

The Properties of Light are

${\star}$ light travels in a straight line unless there is a change in medium or its optical density.

${\star}$ when light falls on a very smooth surface it reflect bags and between the normal the angle of incidence and angle of reflection is same.

${\star}$ whenever there is a change in the optical density of medium the light ray slightly bend inwards when there is are high relative optical density.

${\star}$ light travel in form of photons in both the nature of wave and particle.
