Assertion: If the whole apparatuis of Young's experiement is immersed in liquid, the fringe width will decrease.

Reason: The wavelength of light in water is more than that in air.

View answer and explanation

Correct option: C

Assertion is true and Reason is false

Option C (Assertion is true and Reason is false) is correct because the fringe width decreases when the apparatus is immersed in a liquid, but the wavelength of light in water is less than that in air.
