Answer to Question #95174 in Mechanics | Relativity for Chandana kundu

Question

Find the fringe width for light of wavelength 700Å, distance between slits is 0.1mm, distance between source and screen 5 cm.

Answer 1

$$Y=\lambda*D/d= 0.035 mm$$

Where Y is fringe width, lambda is wavelength 700 *10^-10m, d is distance between slits 0.1*10^ -3 m, D is distance between source and screen 5*10^-2 m.
