Guess which sound has a higher pitch: guitar or car horn?

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

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

A person is listening to a tone of 500 Hz, sitting at a distance of 450 m from the source of the sound. What is the time interval between successive compressions from the source?
