All resonances are forced vibrations

All resonances are forced vibrations

Subject: Physics

When a body capable of vibration is subjected to the action of an external periodic force, the vibrates irregularly at initial stage but later on vibrates with frequency of the external periodic force. This type…

All harmonics are overtones

All harmonics are overtones

Subject: Physics

In a sample of musical note the tone, which have minimum frequency is called fundamental tone. Except the fundamental tone all other tones are called overtones. The overtones which have frequencies as the simple integral…

What is the difference between Musical Sound and Noise?

What is the difference between Musical Sound and Noise?

Subject: Physics

Musical sound is pleasing to the ears while noise is a distasteful sound. Music has an enjoyable effect on ears and mind, whereas noise appears to be nauseating and an irritation. In a theoretical explanation,…

What is Intensity?

What is Intensity?

Subject: Physics

Intensity: The rate of flow of sound energy through unit area placed normal to the direction of propagation of sound is called intensity. Intensity of a sound determines its loudness. Characteristics of intensity are:…

What is Tone?

Subject: Physics

Tone: A musical sound having a single frequency is called tone. A musical sound, generally consists of a number of components having different frequencies, is called note or tune. A note or tune is a…

Free vibration and Forced vibration

Free vibration and Forced vibration

Subject: Physics

Free vibration: When a body capable of vibration is displaced slightly from its equilibrium position and then left to itself, the body begins to vibrate freely in its own natural way called the free or…

Difference between beats and interference

Difference between beats and interference

Subject: Physics

An interference pattern is produced when two waves of similar frequency traveling in similar direction superimpose, while beats are created when frequencies are faintly dissimilar. Difference between beats and interference are: Beats: 1. When two…

Show graphically how beats are produced?

Show graphically how beats are produced?

Subject: Physics

Graphical analysis of beats: Beats: When two sets of waves of nearly equal frequencies and amplitude are superposed it is found that the amplitude of the resultant wave fluctuates with time from maximum to minimum.…

What are Beats?

What are Beats?

Subject: Physics

Beats: When two sound waves of slightly different frequencies, travelling in a medium along the same direction and superimpose on each other, the intensity of resultant sound at a particular position rises and falls regularly…
