Explanation
If the temperature changes then velocity of wave and its wavelength changes. Frequency amplitude and time period remain constant.
Velocity of sound is independent of frequency. Therefore it is same (v) for frequency n and 4n.
Speed of sound, doesn’t depend upon pressure and density medium at constant temperature.
Frequency of sound does not change with medium, because it is characteristics of source.
Interference, diffraction and reflection occurs in both transverse and longitudinal waves. Polarisation occurs only in transverse waves.
Wave on a plucked string is stationary wave. Light waves arc EM waves. Water waves arc transverse as well as longitudinal.
Transverse wave can propagate in solids but not in liquids and gases.
