Sound and Oscillation

Waves transport energy without transporting matter. The energy transportation is carried by a disturbance,which spreads out from a source.Basically there are there are three types of waves.Mechanical waves,electromagnetic waves and matter waves.These type of waves are well explained below. We are well familiar with different types of waves such as water waves in the ocean, or gently formed ripples on ...

Transverse and longitudinal waves are types of mechanical waves.The basic difference between transverse and longitudinal waves is that in transverse waves particles of waves move perpendicular in the direction of wave while in longitudinal waves particles move horizontally in the direction of wave. Now! Stay with us to know the examples of transverse and longitudinal waves in few minutes. What ...

Simple harmonic motion is the kind of vibratory motion in which body moves back and forth about its mean position.Motion of swing,hand of clock and mass spring system are some simple harmonic motion examples. Simple harmonic motion examples Motion of mass attached to spring Ball and Bowl system Motion of simple pendulum Atoms vibrating in molecules The vibration of the ...

What is Doppler effect? “The apparent change in the frequency due to relative motion between source and observer is known as Doppler effect.” When a listener is in motion toward a stationary source of sound ,the pitch (frequency) of the sound heard is higher than when the listener is at rest.If the listener is in motion away from the stationary ...

“Sound energy passing per second through a unit area held perpendicular to the direction of propagation of sound waves is called intensity of sound.”The sound waves transfer energy from the sounding body to the listener.The intensity of sound depends on the amplitude of sound waves.Intensity is a physical quantity and can be measured accurately.The unit of intensity of sound is ...

  A simple pendulum also exhibits SHM. It consists of a small bob of mass ‘m’ suspended from a light string of length ‘L’ fixed at its upper end.In the equilibrium position O,the net force on the bob is zero and the bob is stationary.Now if we bring the bob to extreme position A,the net force is not zero as ...

What is ultrasonics? The study and application of mechanical vibrations with frequencies beyond the limits of hearing of the human ear i.e ,with frequencies about 20 kHz and upwards.There is no theoretical upper limit to the ultrasonic frequency ,although ultrasonic applications are usually restricted to about 20 MHz.Ultrasonic waves have the same basic properties as sound waves,both being examples of ...

Resonance definition physics Resonance occurs when the frequency of the applied force is equal to one of the natural frequencies of vibration of the forced or driven harmonic oscillator. Associated with the motion of a driven harmonic oscillator, there is a very striking phenomenon, known as resonance. It rises if the external driving force is periodic with a period comparable ...

What is speed of sound? Sound waves can be transmitted by any medium containing particles that can vibrate.They cannot pass through vacuum.However,the nature of the medium will affect the speed of the sound waves.In general,the speed of sound in a liquid is five times that in gases;the speed of sound in solid is about fifteen times that in gases.The speed ...

“Sound is a form of energy that is passed from one point to another as a wave.”Sound is an example of a longitudinal wave.One major reason for learning about sound is that we experience it every moment of our lives in the form of music,noise and communication.From the large vocabulary we have of sounds (e.g clank,ping,bang,pop,hiss) and the different adjectives ...
