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

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

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)

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

elasticity of volume
The distance betweentwo consecutivecompressions or
rarefrations is calledwavelength ofLongitudinal wave
