Question

Given that sound travels in air at 340 m/s, find the wavelength of the waves in air produced by a 20-kHz sound source. If the same source is put in a water tank, what would be the wavelength of the sound waves in water? Speed of sound in water 1,480 m/s. ​

Answer 1

Answer:

Explanation:

speed= wavelength *frequency

340=wavelength*20000hz

wavelength=0.017

Speed of sound in water 1,480 m/s. ​

1480=wavelength*20000

wavelength=1480/20000

wavelength=0.074
