Beats & Doppler Effect

Beats & Doppler Effect

Beats The phenomenon of wavering of sound intensity when two waves of nearly same frequencies and amplitudes traveling in the same direction, are superimposed on...
Standing Waves and Normal Modes

Standing Waves and Normal Modes

The interference of two identical waves moving in opposite directions produces standing waves. For a string with fixed ends, the standing wave is given...
Reflection of waves

Reflection of waves

Reflection of waves A part of the wave is reflected and a part is transmitted into the second medium. If a wave is an incident...
The Principle of Superposition of Waves

The Principle of Superposition of Waves

The Principle of Superposition of Waves The net displacement of any element of the string at a given time is the algebraic sum of the...
Speed of a Travelling wave

Speed of a Travelling wave

Speed of a Travelling wave Wave velocity or phase velocity: The distance covered by a wave in the direction of its propagation per unit time...
Displacement Relation in a Progressive Wave

Displacement Relation in a Progressive Wave

Progressive Wave: A wave that travels from one point of the medium to another is called a progressive wave. A progressive wave may be transverse...
Waves & Types of Waves

Waves & Types of Waves

Waves A wave is a disturbance that travels or propagates and transports energy and momentum without the transport of matter. The ripples on a pond,...
Resonance

Resonance

Resonance If an external force with angular frequency ωd acts on an oscillating system with natural angular frequency ω, the system oscillates with angular frequency...
Free Oscillations or Undamped oscillations

Free Oscillations or Undamped oscillations

Free Oscillations or Undamped oscillations If a body, capable of oscillation, is slightly displaced from its position of equilibrium and left to itself, it starts...
The Simple Pendulum

The Simple Pendulum

The Simple Pendulum An ideal simple pendulum consists of a point-mass suspended by a flexible, inelastic and weightless string from a rigid support of infinite...
