Two sounding bodies are producing progressive waves given by $y_{1} = 4 sin (400 π t)$ and $y_{2} = 3 sin (404 π t)$ , where $t$ is in second, which superpose near the ears of a person. The person will hear:

Options:

Answer:

Solution:

Frequencies are 200 Hz and 202 Hz, so the beat frequency is 2 Hz. $I_{ma x} / I_{min} = (\frac{4 + 3}{4 - 3})^{2} = 49$ .
