Two coherent monochromatic light beams of intensities 4I and 9I are superimposed. The difference between the maximum and minimum intensities in the resulting interference pattern is xI. The value of x is ______.

Correct answer

0

Step-by-step solution

aligned & I _ = ( I ₁ + I ₂ )^2 & =( 4 I + 9 I )^2=25 I & I _ = ( I ₁ - I ₂ )^2 & =( 4 I - 9 I )^2= I & I _ - I _ =24 I & x =24 aligned
