Q143 / 160 · AP EAMCET 2023 (18 May Shift 1) · Physics

Angular width of central maximum of a diffraction pattern due to a single slit does not depend upon

Correct answer
A
Distance between slit and source
B
Wavelength of light used
C
Width of the slit
D
Frequency of light used

Solution

Angular width of central maxima is given by, $\mathrm{Q}=2 \lambda \mathrm{a}$ Where, $\lambda=$ Wavelength $\mathrm{a}=$ Width of slit, It does not depend on distance between slit and source.

Hence, the correct answer is option: 'A'.
