Assertion: If width of one slit in Young's double slit experiment is slightly increased, then maximum and minimum both intensities will increase. Reason: Intensity reaching from that slit on screen will slightly increase.

If the separation between the slits in a Young's double slit experiment is increased. What happens to the fringe width? If the separation is increased too much will the fringe pattern remain detectable?

The width of one of the two slits in a Young's double slit experiment is double of the other slit. Assuming that the amplitude of the light coming from a slit is proportional to the slit width, find the ratio of the maximum to the minimum intensity in the interference pattern.

The width of one of the two slits in a Young's double slit experiment is double of the other slit. Assuming that the amplitude of the light coming from a slit is proportional to the slit width, find the ratio of the maximum to the minimum intensity in the interference pattern.
