Dear Student
The amplitude of first wave=10 and of 2nd wave=5Maximum intensity=(a1+a2)2Minimum=(a1-a2)2Ratio=32:1=9:1Hope this information will clear your doubts about topic
  If you have any more doubts just ask here on the forum and our experts will try to help you out as soon as possible

Solve this: 16. The light waves having displacements y 1 = 10 sin ωt - kx and y 2 = 5 sin ωt - kx + ϕ interfere. The ratio of maxirnum to the minimum intensity of light in the interference pattem is (1) 9:1 (2) 3:1 (3) 2:1 (4) 81:1

Solve this:

16. The light waves having displacements $y_{1} = 10 \sin (ωt - kx) and y_{2} = 5 \sin (ωt - kx + ϕ)$ interfere. The ratio of
maxirnum to the minimum intensity of light in the interference pattem is
(1) 9:1 (2) 3:1
(3) 2:1 (4) 81:1
