Audible Range of Human Hearing

Ultrasound and Its Characteristics

Explain how 'echo' is produced.

What should be the minimum distance between the listener and the reflector to hear an echo of sound propagating with a speed v m s⁻¹?

Does the speed of sound increase or decrease on a hotter day? Justify.

Establish the relationship between speed of sound, its wavelength and frequency. If speed of sound in air is 340 m s⁻¹, calculate.
