Two periodic waves of intensities I₁ and I₂ pass through a region at the same time in the same direction. The sum of the maximum and minimum intensities is

Options

  1. A2 ( I ₁+ I ₂ )
  2. BI ₁+ I ₂
  3. C( I₁ + I₂ )^2
  4. D( I₁ - I₂ )^2

Correct answer

A. 2 ( I ₁+ I ₂ )

Step-by-step solution

aligned & I_ max = ( l₁ + l₂ )^2 & I_ min = ( l₁ - I₂ )^2 & I_ max +I_ min =2 (I₁+I₂ ) aligned
