Question

What is the difference between reflection and refraction?​

Answer 1

Reflection is the bouncing back of a ray of light from a surface.

Refraction is the slight deflection of a ray of light while passing through mediums of different density.

Answer 2

Differences between reflection and refraction are:

Reflection:

1. The bouncing back of light is called reflection.

2. It involves only a single medium.

3. After reflection, only change in direction takes place.

4. This phenomenon takes place in mirrors.

5. The angle of incidence is always equal to angle of reflection.

Refraction:

1. The phenomenon of bending of light is called refraction.

2. It involves two or more than two media.

3. After refraction, changes in direction and velocity take place.

4. This phenomenon takes place in lenses.

5. The angle of incidence is not equal to angle of refraction.
