Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
The pitch or frequency of the whistle of a moving train appears to increase as the sound source approaches a stationary observer.
Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
Sound is always produced by some vibrating body. The vibrating body excites mechanical waves in the surrounding medium.
Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
The mechanical erergy is transferred through the vibration of the string.

Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
When two progressive waves of same amplitude and wavelength travelling along a straight line in opposite directions superimpose on each other, stationary waves are formed.
Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
Progressive wave originating from a point source and propagating through an isotropic medium travel with equal velocity in all directions.
Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
A string is a cord whose length is very long compared to its diameter and which is uniform and flexible.
Oscillations
Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
In a mechanical vibration, the particles have both kinetic energy and potential energy.
Theory of resonant vibrations, Examples, Simple experiment on Resonance
Subject and UNIT: Engineering Physics: Unit III: a. Oscillations
It is a special case of forced vibration The phenomenon of making a body vibrate with its natural frequency under the influence of another vibrating body with the same frequency is called resonance.
