if the velocity of a wave in a medium is 1400m/sec and its wavelength is 1.5 km . calculate its frequency . is it in audible range for us? state reasons

velocity of wave = wavelength ×,frequency
1400 m/sec = 1.5× 10³ × frequency
frequency = 1400/1500 = 14/15 Hz
no, this is not in audible range , becoz audible range (20 Hz - 20, 000 Hz )
1400 m/sec = 1.5× 10³ × frequency
frequency = 1400/1500 = 14/15 Hz
no, this is not in audible range , becoz audible range (20 Hz - 20, 000 Hz )

velocity = 1400m/sec
wavelength = 1.5 km = 1500 m
frequency = velocity/wavelength
= 1400/1500
= 0.933 Hz
so, its not in audible range cuz range of hearing is frm 20Hz to 20 KHz
