Question

Ultrasonic, infrasonic and audible sound waves respectively have
velocities U,I & A in a certain medium, then ratio of which of these is 1
A U:A+
BA+U:I+A
CA+U:1
DA-U:A+U​

Answer 1

Answer:

ANSWER

Velocity of sound wave in a medium is given by

v=

ρ

K

where K is the bulk modulus and ρ is the density.

The classification of sound waves based on wavelength(λ) is independent of speed of sound in the medium( speed depends on properties of a medium).

Hence, V

u

, V

i

and V

a

are all equal.
