Question

a bat can hear sound at frequency up to 120hz .Determine the wavelength of sound in air at this frequency .Take the speed of sound in air as 344m/s

Answer 1

Hi friend
-------------
Your answer
-------------------

FREQUENCY = 120Hz

WAVE VELOCITY = 344m/s

WAVELENGTH =?

NOW,
--------

WAVE VELOCITY = FREQUENCY × WAVELENGTH

WAVELENGTH = WAVE VELOCITY/ FREQUENCY

WAVELENGTH = 344/120 m

WAVELENGTH = 2.8666 m. (approximately)
