PhysicsEasysingle choice

Two light waves of intensities $I_{1}$ and $I_{2}$ having same frequency pass through the same medium at a time in the same direction and interfere. The sum of the minimum and maximum intensities is

Options:

Answer:

Solution:

$I_{max} = {(a_{1} + a_{2})}^{2}$

$I_{min} = {(a_{1} - a_{2})}^{2}$

$I_{max} + I_{min} = a_{1}^{2} + a_{2}^{2} + a_{1}^{2} + a_{2}^{2}$

$= 2 (a_{1}^{2} + a_{2}^{2})$

$= 2 (I_{1} + I_{2})$
