A dolphin can typically hear sounds with frequencies up to 150 kHz. What is the speed of sound in water if a wave 

      with this frequency has a wavelength of 1.0 cm?

Speed = _________________    Wavelength = ___________________   Frequency = _____________________

Formula: _____________________________

Solution:

to find: speed of wave

  • speed=v
  • wavelength, w = 1.0 cm
  • :: 1cm = 0.01 m
  • frequency , f = 150 kHz 
  • :: 1 kHz = 1000 Hz
  • 150kHz=150000Hz
  • formula : frequency x wavelength=speed
  • i.e.,  f * w = v

so now ,

0.01 * 150000 = speed

1500 m/s = speed
