The phenomenon of sound propagation in air is

The frequency of a sound wave propagating in air is 3000 Hz. The waves are propagating from a region where T = 30^(@) C to the region where T = 20^(@)C . What will be the percentage change of wavelength ?

Consider sound waves in air, electromagnetic waves in the visible region and transverse wave on a string . The phenomenon of polarisation can be observed in

Newton assumed that sound propagation in a gas takes under
