Question

A sound wave has a frequency of 15kHz and wavelengths 70cm how much time will in take to travel a distance of 2km​

Answer 1

speed of

sound = wavelength ×frequency

=0.70×15000Hz

=10500.00m/sec

speed=distance/Time

10500m/sec=1000m/Time

10500/1000 =Time

10.5sec = Time(Answer)(｡•́︿•̀｡)
