In Young?s double slit experimental setup, if the wavelength alone is doubled, the band width $\beta$ becomes
In Young?s double slit experimental setup, if the wavelength alone is doubled, the band width $\beta$ becomes
Updated On: Jun 6, 2022
- $\frac{\beta}{2}$
- $2\beta$
- $4\beta$
- $\beta$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In Youngs double slit experiment
Band width $\beta=\frac{\lambda D}{2 d}$
$\beta \propto \lambda$
If the wavelength is doubled, then band width $\beta$ become double.
Band width $\beta=\frac{\lambda D}{2 d}$
$\beta \propto \lambda$
If the wavelength is doubled, then band width $\beta$ become double.
