Question

In a Young’s double slit experiment, the screen is separated from double-slit by 1.2 m. The distance between the two slits is 0.030 mm. Calculate the distance between adjacent bright fringes. (Given, the wavelength of the light used is λ=560 nm).

Answer 1

Answer:

0.0224

Explanation:

B=¶d/D

where B is the bandwidth

¶ is lambda the wavelength

d distance b/w slits

D distance b/w fringes

D=¶d/D

=560×10^-9×1.2/0.030×10^-3

=0.0224m
