Factors Affecting Speed of Sound

Two friends b...

Question

Two friends blow two whistles at the same time. The first whistle makes a sound whose frequency is twice that of the sound made by the other whistle. Which sound will reach you first ?

Solution

Sounds from both whistles will reach to us at the same time because speed of sound doesn't depend upon frequency (whereas frequency depends upon speed of wave) but on the medium properties , as the medium is same for both whistles therefore they will reach together to us .
