List of top Physics Questions on Youngs double slit experiment asked in KEAM

The width of a fringe is $0.5 \text{ mm}$ in Young’s double slit experiment for a light of wavelength $500\text{ nm}$. If the wave length of light alone is changed to $600 \text{ nm}$, the width of the fringe becomes}

In Young’s double slit experiment, the screen is placed 1m away from the coherent sources. If the wavelength of light used changes from 500 nm to 600 nm the fringe width increases by 0.25mm. The distance between the slits in mm is

In a Young's double slit experiment with a light having wavelength 500 nm, separation between slit is 0.2 mm, distance between slit and screen is 2m. Find fringe width.
