If Young's double-slit experiment is performed under water, how would be observed interference pattern be affected ?

Explanation

To analyze how the interference pattern in Young's double-slit experiment is affected when performed underwater, we can follow these steps:

### Step 1: Understand the Basics of Young's Double-Slit Experiment
In a typical Young's double-slit experiment, light passes through two closely spaced slits and creates an interference pattern on a screen due to the superposition of light waves emanating from the two slits.

### Step 2: Consider the Speed of Light in Different Mediums
The speed of light in a vacuum is denoted as \( c \). However, when light travels through a medium like water, its speed decreases. The speed of light in water is given by:
