Explain why sound travels faster in water than in air. Include a brief explanation related to the medium's properties.

An object moving at a speed greater than that of sound is said to be moving at

Speed of Sound in Different Media

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.
