Two coherent monochromatic light beams of intensities I and 41 are superposed. The maximum and minimum possible intensities in the resulting beam are

Answer»

5I and I
9I and I
5I and 3I
9I and 3I

Solution :`I_(MAX)=(SQRT(I_(1))+sqrt(I_(2)))^(2)=(sqrt(4I)+sqrt(I))^(2)=9I`
`I_(max) = (sqrt(I_(1))-sqrt(I_(2)))^(2)=(sqrt(4I)-sqrt(I))^(2)=I`
