Ratio of intensity of two waves is 25 1
Asked by admin @ in Physics viewed by 295 People
ratio of intensity of two waves is 25:1.The ratio of maximum and minimum intensities produced by their interference will be
Answered by admin @
Explanation:
Assume there are two waves of amplitudes A1 and A2 with no loss of generality assume A1>A2.
These two waves upon being superimposed would give us waves:
Maximum amplitude = A1+A2
Minimum amplitude = A1−A2
Since intensity is proportional to the square of amplitude.
IminImax=(A1−A2A1+A2)2
Upon substituting this ratio = 25 and solving,
We get, A2A1=23
Hence both assertion and reason are true, reason is the correct explanation,
Hence option A.
