What is the ratio of the slit width when amplitudes of light wave from two slits have ratio rt2 : 1? Share with your friends Share 2 Ved Prakash Lakhera answered this We know that relation of slit width to intensity of light wave is ω1ω2=I1I2=A12A22 ω1ω2= 2212=41Thus the ratio of slit width is 4:1. 3 View Full Answer
