Waves

This topic introduces the movement of air with disturbing patterns. It also explains different kinds of waves and the concept of restoring force proportionally. The constant of electromagnetic waves in a vacuum is also discussed here in detail.

This topic discusses the classification of waves on the basis of their direction of travelling as transverse or longitudinal waves. It also explains the capillary, gravity and harmonic waves with illustrations for a better understanding.

This topic explains the direction of waves in transverse or longitudinal waves. It also explains the capillary and gravity waves. The harmonic wave is also illustrated here.

This topic gives mathematical description of a progressive wave. We will learn about the sinusoidal travelling wave and meaning of some standard symbols. It also shows the figure of harmonic wave progressing along the positive direction.

The topic elaborates on the speed of a transverse wave on a stretched string through solved examples. It also explains the speed of a longitudinal wave with illustration here.

The topic explains the pulses having equal and opposite displacements through diagrammatic representation. It also explains the principle of superposition of waves through examples.

This topic explains the refracted waves of a pulse meeting a rigid boundary. It also explains standing waves and normal waves. The concept of the first and second harmonic is also illustrated here.

In this topic, we will learn about the stationary with nodes, anti-nodes and normal modes. It discusses the standing waves arising from two harmonic waves travelling in opposite directions. The concept of first and second harmonic is also illustrated here.

This topic explains the history of beats and reflection of sound in an open pipe. It also explains the superposition of two harmonic waves having different frequencies illustrated with the diagrammatic representation.
