Two periodic waves of intensities I_1 and I_2 pass through a region at the same time in the same direction. The sum of the maximum and minimum intensities is

Question

Accepted Answer

Correct answer: B. (b) Other factors such as (f) and v remaining the same, I=A^2 constant K, or A= lK On superposition A_ max=A_1+A_2 and A_r=A_1-A_2 A_ max^2=A_1^2+A_2^2+2A_1A_2 = I_ maxK= I_1K+ I_2K+ 2 I_1I_2K A_ min^2=A_1^2+A_2^2-2A_1A_2 = I_ minK= I_1K+ I_2K- 2 I_1I_2K I_ max+I_ min=2I_1+2I_2

$Two periodic waves of intensities I_{1} and I_{2} pass through a region at the same time in the same direction. The sum of the maximum and minimum intensities is$
