Question 135: Waves Optics

Question

In a Young’s double slit experiment, light of
500 nm is used to produce an interference
pattern. When the distance between the slits
is 0.05 mm, the angular width (in degree) of
the fringes formed on the distance screen is
close to

Accepted Answer

$$\beta $$ = $${{\lambda D} \over d}$$
and $$	heta $$ = $${\beta  \over D}$$
$$ \Rightarrow $$ $$	heta $$ = $${\lambda  \over d}$$
= $${{500 	imes {{10}^{ - 9}}} \over {0.05 	imes {{10}^{ - 3}}}}$$
= 0.01 rad
