How are the wavelength and frequency of a sound wave related to its speed?

Sound wave is

Speed of sound wave is

How are velocity,wave length and frequency related?

Calculate the wavelength of a sound wave whose frequency is 220 Hz and speed is 440m/s in a given medium'.

What are wavelength, frequency, time period and amplitudes of a sound wave?

A person has a hearing range from 20 Hz to 20 kHz. What are the typical wavelengths of sound waves in air corresponding to these two frequencies? Take the speed of sound in air as 344 m s^-1 .

A train whistling while approaching a railway platform with a speed of 90 km(s)^-1 .The frequency of sound of the whistle is 600 Hz.If the velocity of sound in air is 325 m(s)^-1 ,calculate the apparent frequency of the sound of the whistle as heard by an observer standing on the platform.
