Question 514: Waves

Question

Two sound waves with wavelengths 5.0 m and 5.5. m respectively, each propagate in a gas with velocity 330 m/s. We expect the following number of beats per second.

Accepted Answer

Frequencies of sound waves are
$${{330} \over 5}$$ & $${{330} \over {5.5}}$$
i.e.,  66 Hz and 60 Hz
Frequencies of beat = 66 Ã¢ÂÂ 60 = 6 per second
