Waves

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 covers concepts such as Terms in Wave Motion, Frequency and Time Period, Amplitude, Angular Frequency, Angular Wave Number, Displacement Function for a Transverse Wave, Wave Speed, Relation among Wave Speed, etc.

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.

This topic covers concepts such as Speed of Sound Waves, Pressure and Speed of Sound Wave, Speed of Sound Waves in Liquids, Derivation of Velocity of Longitudinal Waves in an Elastic Medium & Factors Affecting Speed of Sound in Gases, etc.

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.

This topic sheds light on the principle of superposition of waves. It covers some graphs that describe the applications of this principle. In addition, it talks about the interference of waves via this principle.

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.

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 effect of frequency while increasing and decreasing the pitch of the sound. We will also learn the effect that occurs when source and observer moves.
