Young's double slit experiment is performed in water, instead of air, then fringe width
- A decreases.
- B becomes infinite.
- C increases.
- D remains same.
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.
\(\mathrm{X}=\frac{\lambda \mathrm{D}}{\mathrm{d}}\)
In water the wavelength \(\lambda\) decreases and hence the fringe width decrease.
