Q. In Young’s double slit experiment, to increase the fringe width
KEAM
KEAM 2014
Wave Optics
A
the wavelength of the source is increased
94%
B
the source is moved towards the slit
0%
C
the source is moved away from the slit
0%
D
the slit separation is increased
0%
E
the screen is moved towards the slit
0%
Solution:
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 $\lambda$
