Question

Ultrasonic, infrasonic and audible sound waves propagate through same medium with speed V1,
V2 and V3 respectively at constant temperature, then
(A) V1 = V2 = V3
(B) V1 > V3 > V2
(C) V1 < V3 < V2
(D) V1 < V2 < V3
​

Answer 1

Answer:

B is correct because ultrasonic are more fast then infrasonic and infrasonic are fast then audible
