A sound wave is the pattern of disturbance caused by the energy travelling away from the source of the sound. Sound waves are longitudinal waves. This means that the propagation of vibration of particles is parallel to the energy wave propagation direction.

Waves gives general information about waves, including vocabulary and equations. Reflection and Superposition describes what happens when two waves share space within a medium. Sound & Music describes the properties and equations of …

This Physics Tutorial discusses the nature of sound, its characteristic behaviors, and its association with the operation of musical instruments. Attention is given to both the purely conceptual aspect of sound waves and to the mathematical treatment of the same topic.

Oct 1, 2024 · Learn about sound for your IGCSE Physics exam. This revision note includes longitudinal wave features, such as compression and rarefaction.

Sound Waves:-It is the form of energy which produces, in us, the sensation of hearing. Properties:-(a) Longitudinal in nature. (b) It requires a material medium for its propagation. (c) Sound waves can be reflected. (d) Sound waves suffer refraction. (e) Sound waves show the phenomenon of interference (f) Sound waves shows diffraction

Lecture Video: Sound Waves. Sound wave, a longitudinal wave, is discussed in this lecture. Prof. Lee calculates the speed of sound using two extreme cases: (1) constant temperature (2) adiabatic process. He also measures the speed of sound using an in-class demo.

In many instances, sound is a periodic wave, and the atoms undergo simple harmonic motion. Thus, sound waves can induce oscillations and resonance effects (Figure 17.2.2 17.2. 2).

Aug 24, 2017 · → Wave is a disturbance which travels through a medium and carries energy. → So sound travels in wave form known as mechanical waves. • When a body vibrates then it compresses the air surrounding it and form a area of high density called compression (C).

Jan 14, 2025 · Revision notes on Sound Waves for the Cambridge (CIE) O Level Physics syllabus, written by the Physics experts at Save My Exams.

In the case of a sound wave moving from the church choir to the pews, the medium through which the sound wave travels is the air in the room. The Terms Wave Length, Frequency and Velocity of a Wave. Explain the terms wave length, frequency and velocity of a wave. Consider the transverse wave below:
