## Important Topics for HC Verma Concepts of Physics Part-1 Chapter 16: Sound Waves

The Propagation of Sound Waves

Sound is a system of waves of pressure that circulates through compressible media such as air or water. Sound can transmit through solids as well, but there are added modes of propagation. During their propagation, waves can be reproduced, refracted, or weakened by the medium.

Displacement Wave

Particle displacement is also known as displacement amplitude. It is a quantity of distance of the movement of a sound element from its equilibrium location in a medium as it conducts a sound wave. The SI unit of particle displacement is calculated in metre (m).

Pressure Wave

A wave in which the propagated disruption is a deviation of pressure in a substantial medium. It is also known as P-wave.

The Intensity of Sound Waves

Sound intensity is also called acoustic intensity. It is described as the power sustained by sound waves per unit area in a way perpendicular to that area. The SI unit of intensity, which contains sound intensity, is the watt per square meter (W/m2).

Sound intensity: I, SIL

Sound pressure: p, SPL,LPA

Doppler Effect

The Doppler Effect is used to calculate the speed at which stars and galaxies are approaching or retreating from us, in a phenomenon named red shift or blue shift. Redshift occurs when light seen coming from a body that is moving away is proportionally greater than before in wavelength or shifted to the red end of the spectrum.

Sonic Booms

A sonic boom is a sound related to the shock waves produced whenever a body moving through the air faster than the speed of sound. Sonic booms produce huge amounts of sound energy, sounding identical to an eruption or a thunderclap to the human ear.

Laplace’s Correction

A correction to the control of the speed of sound in a gaseous medium. Newton supposed that the pressure-volume alterations that happen when a sound wave movements through the gas are isothermal. Laplace was, therefore, able to attain agreement among theory and experiment by supposing that pressure-volume variations are adiabatic.
