Question:
In Young?s double slit experiment, to increase the fringe width
In Young?s double slit experiment, to increase the fringe width
Updated On: Mar 4, 2024
- the wavelength of the source is increased
- the source is moved towards the slit
- the source is moved away from the slit
- the slit separation is increased
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Increase the fringe width depend only the wavelength of the source is increased.
By Young's double slit experiment
$W=\frac{D \lambda}{d}$
According to equation, the fringe width is directly proportional to $\lambda$
By Young's double slit experiment
$W=\frac{D \lambda}{d}$
