  1. A decreases.
  2. B becomes infinite.
  3. C increases.
  4. D remains same.
Verified Solution

Answer & Solution

Correct Answer

(A) decreases.

Step-by-step Solution

Detailed explanation

(C)
\(\mathrm{X}=\frac{\lambda \mathrm{D}}{\mathrm{d}}\)
In water the wavelength \(\lambda\) decreases and hence the fringe width decrease.
