JEE PYQ: Waves And Sound Question 22
Question 22 - 2020 (09 Jan Shift 1)
Three harmonic waves having equal frequency $v$ and same intensity $I_0$, have phase angles $0$, $\frac{\pi}{4}$ and $-\frac{\pi}{4}$ respectively. When they are superimposed the intensity of the resultant wave is close to:
(1) $5.8 I_0$
(2) $0.2 I_0$
(3) $3 I_0$
(4) $I_0$
Show Answer
Answer: (1)
Solution
The resultant amplitude from superposition gives intensity close to $5.8 I_0$.
