Vibration of String

Science > Physics > Stationary Waves > Vibration of String In this article, we shall study different modes of vibrations of string, the expression for its fundamental frequency of vibration. Concept of Overtones: Whenever a string or an air column is set into vibrations, the vibrations consist of the fundamental frequency accompanied by certain higher […]

Sonometer Experiment

Science > Physics > Stationary Waves > Sonometer Experiment In this article, we shall study construction and working of sonometer, and its use to verify the laws of string. Laws of Vibrating String: Law of Length: If the tension in the string and its mass per unit length of wire remains constant, then the frequency […]

Doppler Effect

Science > Physics > Wave Motion > Doppler Effect In this article, we shall study the Doppler effect in case of sound waves and a brief idea of the Doppler effect in case of light. Doppler Effect: The apparent change in the frequency of the sound heard by an observer, due to relative motion between […]
