Calculate the ratio of two points on a screen in a Young's double - slit experiment if the waves from two coherent sourcres have a phase difference of `phi/3` and `phi/2` respectively.

In Young's double slit experiment light waves are coherent. Why?

Find the ratio of intensities at two points on a screen in young’s double slit experiment when waves from the two slits have path difference of 0 and λ/4.

Find the ratio of intensities at two points X and Y on a screen in Young.s double slit experiment where waves from two sources have path difference of zero and "wavelength"//4 repectively.

Find the ratio of intensities at two points on a screen in young’s double slit experiment when waves from the two slits have path difference of lambda//4 .
