Question

sound wave of the wavelength 4cm have a velocity of 344m/s in air. calculate frequency and also stae which type of sound is it?​

Answer 1

Answer:

Velocity of sound wave v=339 ms

−1

Wavelength of the waves λ=1.5 cm =0.015 m

∴ Frequency of the waves ν=

λ

v

=

0.015

339

=22.6 kHz

Audible frequency range for human ear lies between 20 Hz to 20 kHz

Thus this waves is not audible.
