Question

refractive index is less than 1 is this possible? justify...... the best answer will be marked as brainliest

Answer 1

Answer:

yes it is possible

Explanation:

this is when the Ray of light passes from the denser to rarer medium in a oblique manner the velocity of the Ray obviously increases, hence, decreasing the refractive index to less than 1

Answer 2

Answer: yes we can have refractive index less than 1 in some case .

Like we all have read that speed of light in air /speed of light in medium =c/v which will always be greater than 1.
