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?

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
