Question:
In a Young's double slit experiment, light of $500 \mathrm{~nm}$ is used to produce an interference pattern. When the distance between the slits is $0.05 \mathrm{~mm}$, the angular width (in degree) of the fringes formed on the distance screen is close to :
Correct Option: , 2
Solution:
(2) Given : Wavelength of light, $\lambda=500 \mathrm{~nm}$
Distance between the slits, $d=0.05 \mathrm{~mm}$
Angular width of the fringe formed,
