1.	Two coherent monochromatic light beams of intensities I and `4I` are superposed. The maximum and minimum possible intensities in the resulting beam areA. (a) `5I` and `I`B. (b) `5I` and `3I`C. (c) `9I` and `I`D. (d) `9I` and `3I`
Answer» Correct Answer - C `I_(max)=(sqrt(I_1)+sqrt(I_2))^2=(sqrtI+sqrt(4I))^2=9I` `I_(min)=(sqrt(I_1)-sqrt(I_2))^2=(sqrtI-sqrt(4I))^2=I`
