Question

A source emits sound of frequency 600 Hz inside
water. The frequency heard in air will be equal
to (velocity of sound in water = 1500 m/s, velocity
of sound in air = 300 m/s)
(a) 3000 Hz (b) 120 Hz
(c) 600 Hz (d) 6000 Hz

Answer 1

Answer:

Frequency of the a particular wave remains constant in all medium, but its velocity as well as wavelength vary with medium.Thus the source emits sound of frequency of $$600 Hz$$ inside water and in air also.
