ICSE 9 Physics Propagation of Sound Waves

WebA sound wave is fundamentally a pressure disturbance that propagates through a medium by particle interaction. In other words, sound waves move through a physical medium by alternately contracting and expanding the section of the medium in which it propagates.

WebPropagation of Sound Waves Class 9 - Concise Physics Selina Solutions Exercise 8 (A) Question 1 What causes sound? Answer Sound is produced when a body vibrates. … WebWhen a sound wave is incident on a solid or liquid surface, it bounces back onto the same medium. This is known as the reflection of sound. Like light, sound too undergoes reflection from any hard surface and obeys the same laws of reflection, which light obeys. WebAug 9, 2015 · A wave is a disturbance which moves through a medium by the vibration of the particles of the medium. So sound is considered as a wave. Since sound waves are produced due to the vibration of particles of the medium sound waves are called mechanical waves. 4.

Reflected ray: The light ray obtained after reflection from the surface in the same medium as the incident ray is called the reflected ray. Normal: The perpendicular drawn to the surface at the point of incidence is the normal.

WebA transverse sinusoidal wave of amplitude a, wavelength λ and frequency f is travelling on a stretched string. The maximum speed of any point on the string is v / 10, where v is the speed of propagation of the wave. If a =10 3 m and v =10 m / s, then λ is given by A. λ=10 3 mB. λ=π× 10 2 mC. λ=2 π× 10 2 mD. λ=10 2 m
