Question

Two sound waves have wavelength 85/170 and 85/172 m in air .each wave produces 4 beats per second with a third note of fixed frequency .find the frequency of the third note and sound in air

Answer 1

Explanation:

Each of these notes produce 4 beats/sec with a third note of fixed frequency. Find the frequency of third note and velocity of sound in air. Ans Data :- 2y = 85/170 m 22 = 85/172 m No. Beats = 4 Frequency =n=2 Yolcitofa.
