Question

Light travels slower in a rarer medium as compared to that in a denser medium.

• A. True
• B. False

Answer 1

The correct option is B False

1. The speed of light depends on the optical media that it travels through.
2. As the optical density of the medium increases, the speed of light decreases as the closeness of the particles will create a hindrance to the movement of the light through it.
3. The higher the optical density, the lower the speed of light
4. In other words, the light will travel slower through an optically denser medium than through an optically rarer medium.

Hence, the given statement is false.
