AIPMT 2008 | Waves Question 42 | Physics

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

$${\left( {\sqrt {{I_1}} - \sqrt {{I_2}} } \right)^2}$$

$$2\left( {{I_1} + {I_2}} \right)$$

$${{I_1} + {I_2}}$$

$${\left( {\sqrt {{I_1}} + \sqrt {{I_2}} } \right)^2}$$
