    \[\Huge{\color{blue}{\rightarrow \boxed{\mathbb{\text{Waves}}}}}\] \[\huge \color{red} {-Wave \space Motion: } \]Wave motion is that mechanism by which energy is transferred from one point to another in the form of wave.Waves transport energy without transporting matter.The energy transportation is carried by disturbance,which spreads out from a source. \[\LARGE{1)Mechanical \space Waves: }\]The waves which require a material medium for their propagation,are known as mechanical waves. \[\LARGE{2)Electromagnetic \space Waves: }\]Electromagnetic waves are those waves which can pass through vacuum.They do not require any material medium for their propagation.For example , radio and television waves,heat radiation,light and gamma rays. \[\LARGE{3)Matter \space Waves: }\]A moving particle carries energy from one place to another in the form of kinetic energy.Since energy is carried by waves,therfore the waves associated with such moving particles are known as matter waves.

    \[\huge \color{red} {-Progressive \space Waves:} \]A wave,which transfers energy in moving away from the source of disturbance,is called a progressive or travelling wave.There are two kinds of progressive waves-transverse wave and longitudinal waves.The train of wave pulses moving uniformly along the string is called a travelling wave and has the shape of a sine wave.

    \[\Huge{\bf{Periodic \space Waves:}}\] Continuous , regular and rhythmic disturbance in a medium result from periodic vibrations of a source which cause periodic waves in that medium.A good example of a periodic vibrator is an oscillating mass-spring system.

    \[\Huge{\bf{Amplitude:}}\]The amplitude of the wave is the maximum value of the displacement in a crest or trough and it is equal to the amplitude of the vibrator.

    \[\Huge{\bf{Wavelength: }}\]The distance between any two consecutive crests or troughs is the same all along the length of the rope.This distance is called the wavelength of the periodic wave and is usually denoted by the Greek letter Lambda.

    \[\Huge{\bf{Frequency: }}\]It is defined as the number of wave pulses passing a certain place or point in one second.It is denoted by f .Its unit is cycles*s^-1

    \[\Huge{\bf{Speed:}}\]The speed of a wave can be measured by timing the motion of a wave crest over a measured distance.But it is not always convenient to observe the motion of the crest.However,the speed of a periodic wave can be found indirectly from its frequency and wavelength. \[v=\frac{ \lambda }{ T }\] Since,\[\frac{ 1 }{ T }=f\] Therfore,\[v=f \lambda \]

    \[\huge \color{red} {-Longitudinal \ Periodic \ Waves:} \]The wave in which the various particles of the medium vibrate about their mean position along the direction of the waves are know as longitudinal periodic waves. Also,the distance between two consecutive elongations is know as one wavelength.

    \[\huge \color{red} {-Speed \ of \ Sound \ in \ Air:} \]Sounds waves are the most important examples of longitudinal waves.The speed of sound waves depend on the compressibility and inertia of the medium through which they are travelling.If the medium has the elastic modulus E and density p then,Speed v is given by ,\[V=\sqrt{\frac{ E }{ \rho }}\] The speed of sound is much higher in solids than in gases. \[\Large{\bf{Newton's \ Formula \ for \ the \ speed \ of\ sound :}}\]Newton's formula for speed of sound is : \[v=\sqrt{\frac{ P }{ \rho }}\]

    \[\Large \color{red} {-Laplace\ Expression \ for \ the \ speed \ of sound:} \]Using newtons formula for the speed of sound,we find that the speed of sound in air comes out to be 280 m/s.wheras its experimental value is 332 m/s .to account for the difference,Laplace pointed out that the compressions are rarefractions occur so rapidly that heat of compressions remains confined to the region where it is generated and does not have time to flow to the neighbouring cooler regions which have undegone an expansion.Hence the temperature of the medium does not remain constant.Hence we have Laplace expression for the speed of sound in a gas as given by,\[v=\sqrt{\frac{ \gamma P }{ \rho }}\]

    The Expression above gives the speed of sound in air to be 333 m/s.which is very close to the experimental value.
