Constructive Interference and Intensity
Two coherent light sources of equal amplitude produce waves that interfere constructively at a point. If the amplitude of one source is tripled while the other remains constant, by what factor does the intensity at that point increase?
A
The intensity increases by a factor of 9
B
The intensity increases by a factor of 16
C
The intensity increases by a factor of 3
D
The intensity increases by a factor of 4
