Question:
The width of the diffraction band varies
The width of the diffraction band varies
Updated On: Jan 18, 2023
- inversely as the wavelength
- directly as the width of the slit
- directly as the distance between the slit and the screen
- inversely as the size of the source from which the slit is illuminated
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Width of the diffraction band is given by
$\beta=\frac{\lambda D}{d}$
where $D=$ distance between slit and the screen
$\lambda=$ wavelength of light used and
$d=$ width of slit.
Hence, width of the diffraction band varies directly as the distance between the slit and the screen.
$\beta=\frac{\lambda D}{d}$
where $D=$ distance between slit and the screen
$\lambda=$ wavelength of light used and
$d=$ width of slit.
Hence, width of the diffraction band varies directly as the distance between the slit and the screen.

Single Slit Diffraction
In the single-slit diffraction experiment, we can examine the bending phenomenon of light or diffraction that causes light from a coherent source to hinder itself and produce an extraordinary pattern on the screen called the diffraction pattern.
