How Sound Waves propagate? Sound wave are wave motion which travels through a medium due to vibrations of medium particles about their mean position. All properties of wave motion are applicable to motion of sound
What are called Stationary Waves? When two identical waves of same amplitude, same frequency, same speed moving in same path but opposite in directions are superpose on each other, the resultant wave doesn’t travel in
What is meant by Phase of a wave? Phase of a wave is the quantity which gives complete information of the medium particle at any instant of time at a particular position of wave motion.
What is called a Compound Pendulum? A compound pendulum is a rigid body pegged and hanged freely to oscillate about a smooth horizontal axis passing through the peg. Consider about a rigid body ( compound
What is Harmonic Wave Equation? Propagation of a disturbance ( a wave ) which travel through a medium due to vibrations or oscillations of medium particles about their mean position is called a wave motion.
What is an Echo? Echo is a phenomenon of hearing of successive reflected sound waves after hearing the direct sound wave. It is associated with reflection of sound from distant reflecting surface such as high
What is an Organ Pipe? An organ pipe is the simplest musical instrument in which sound is produced by setting an air column into vibrations. Organ pipes are of two types – Open organ pipe
What are Sound Beats? When two sound waves, having slightly different frequencies are made to travel along the same path in the same direction through same medium, they superpose upon each other and the intensity
What is called “Doppler effect”? If there is a relative motion between the source of sound and the observer, the frequency of sound felt by the observer is different from the frequency of sound emitted
What is the speed of Sound? Scientist Newton first stated a theoretical expression for speed of sound in a gaseous medium. Newton’s theory for speed of sound in gases is based on the following assumptions.
What are effects of boundary in Reflection of Waves? When a progressive wave comes in contact with a boundary interface, then reflection of waves or refraction occur depending upon the nature of boundary conditions. Reflection
What is called Amplitude of a Wave? In a wave propagation, particles of the medium oscillates / vibrates to and fro about their mean position. The mean position is called equilibrium position. The displacement of
What is Wave Motion? Propagation of a disturbance ( a wave ) which travel through a medium due to vibrations or oscillations of medium particles about their mean position is called a wave motion. Wave
What is called Resonance? Resonance is a particular case of forced oscillations in which the frequency of the driving force becomes equal to the natural frequency of the oscillating body which results in producing of
What is called a Pendulum? A pendulum is defined as a weight tied at one end of a string which is suspended from a pivot so that it can swing freely under the force of
