A person has a hearing range from 20 Hz to 20 KHz. What is the typical wavelength of sound waves in air corresponding to these frequencies ? Take the speed of sound in air as `344 ms^ -1`.

What is the wavelength corresponding to a freqency of 200 Hz. Given the speed of sound in air is 344 ms^-1

A SONAR system fixed in a submarine operates at a frequency 40.0 kHz. An enemy submarine moves towards the SONAR with a speed of 360 km h^-1 . What is the frequency of sound reflected by the submarine ?Take the speed of sound in water to be 1450m s^-1 .

Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440ms^-1 in a given medium.

Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 40 m/s in a given medium.

A SONAR system fixed in a submarine operates at a frequency 40.0 kHz. An enemy submarine moves towards the SONAR with a speed of 360 kmh^(-1) .What is the frequency of sound reflected by the submarine? Take the speed of sound in water to be 1450 ms^(-1) .
