SOUND WAVES

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 220

WAVES

Wave is defined as an

oscillatory disturbance which

travels through the mediumwithout change of form

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 320

DEFINITIONS

Periodic motion

A motion that repeats itself in equal interval of time iscalled a periodic motion

Oscillatory motionIf a particle makes an to and fro motion about its

mean position the morion is called as oscillatorymotion

Period of OscillationTime taken by the particle to complete oneoscillation is called period

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 420

Frequency

The number of oscillations performed by particle persecond is called as frequency of the oscillation

AmplitudeThe maximum displacement of particle from its mean

position is called amplitude

MECHANICAL WAVES

The waves which require material

medium for their propagationare called mechanical waves

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 720

NON MECHANICAL WAVES

The waves which does not require

material medium for their

propagation are called as non-mechanical waves

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 820

WAVE MOTION

Wave motion is propagation of

disturbance (energy) through the

medium in terms of oscillations of medium particles

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 920

PROGRESSIVE WAVES

The waves which continually advance

through the medium are called progressive

waves

They are of two types

Transverse waves

Longitudinal waves

DIFF BETWEEN LONGITUDINAL amp TRANSVERSE WAVES

Vibration of theparticles of the medium

are parallel

Medium is divided incompressions amprarefractions

Vibration of theparticles of the medium

are perpendicular Medium is divided into

crests and troughs

Pressure and density

For propagationmedium must possess

elasticity of volume

The distance betweentwo consecutivecompressions or

rarefrations is calledwavelength ofLongitudinal wave

MUSICAL SOUNDFINAL SONGS 09 TRACK 9I AM BARBIEMP3

Musical instruments like guitar flute Violinproduce sound having pleasant effect on listener iscalled musical sound

NOISE

Sound produced by shouting of a person

thunderstorms etc produces unpleasant

effect on the listener and are called as

Noise

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 1620

Two musical sounds can be differentiated

from one another based on following

characteristics

Loudness

Pitch

Quality of timbre

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 1720

LOUDNESS

Loudness is the characteristics by which wedifferentiate two sounds having same frequency

Loudness depends on intensity of vibration

The energy of a particle performing vibrations isproportional to the square of amplitude(A) andFrequency (n)

NOISE

Sound produced by shouting of a person

thunderstorms etc produces unpleasant

effect on the listener and are called as

Two musical sounds can be differentiated

from one another based on following

characteristics

Loudness

Pitch

Quality of timbre

842019 Physics Sound Waves

httpslidepdfcomreaderfullphysics-sound-waves 1720

LOUDNESS

Loudness is the characteristics by which wedifferentiate two sounds having same frequency

Loudness depends on intensity of vibration

The energy of a particle performing vibrations isproportional to the square of amplitude(A) andFrequency (n)

PROGRESSIVE WAVES

The waves which continually advance

through the medium are called progressive

waves

They are of two types

Transverse waves

Longitudinal waves

httpslidepdfcomreaderfullphysics-sound-waves 1020

DIFF BETWEEN LONGITUDINAL amp TRANSVERSE WAVES

Vibration of theparticles of the medium

are parallel

Medium is divided incompressions amprarefractions

Pressure and densityat any point of mediumvaries

Vibration of theparticles of the medium

are perpendicular Medium is divided into

crests and troughs

Pressure and density

at any point of mediumdoes not vary

Longitudinal Waves Transverse Waves

elasticity of volume

The distance betweentwo consecutivecompressions or

rarefrations is calledwavelength ofLongitudinal wave
