A progressive sound wave of frequency 500 Hz is travelling
through air with a speed of 350 ms⁻¹. A compression
maximum appears at a place at a given instant. The minimum
time interval after which the rarefraction maximum occurs at
the same point, is
(a) 200 s (b) 1/250 s
(c) 1/500 s (d) 1/1000 s

Answer:
mark me as a brain list
Explanation:
Time period of wave T=
500
1
In one time period there is a maximum of both rarefaction and compression,
hence time after which rarefaction occurs is
2
T
=
1000
