amplitude of sound waves

The measure of the height of a wave or the depth of its trough is called amplitude. Amplitude determines the intensity or brightness of a wave. It is denoted by the letter 'A..

Sound as a Wave - A ringing bell, a thunderclap, laughter, and rock music are sounds that seem very different to us. However, all sounds are alike because they are waves. Let us understand how wave properties can be applied to sound..

Sound is the form of energy propagated as waves which our ears receiv..

Amplitude Modulation - When the amplitude of high frequency carrier wave is changed in accordance with the intensity of the signal, it is called amplitude modulation. In amplitude modulation, only the amplitude of the carrier wave..

When the amplitude of high frequency carrier wave is changed in accordance with the intensity of the signal, it is called amplitude modulatio..

Sound - Sound is always produced due to the vibration of a body. In some cases the vibrations of the source may be very small or very large that it may not be possible to detect them. This type of vibrations is produced by tuning fork, drum, bell, the string of a guitar etc. Hum..

Experiment to Demonstrate Interference of Sound Waves - Interference of sound waves can be demonstrated using Quincke's tube. It consists of two U-tubes ABCDE and FGH, whose limbs can be inserted telescopically into each other. The tube ABCDE is provided with..

Let a long coiled spiral spring be suspended horizontally from a wooden frame using a number of threads. Ordinarily, the turns of the spring will be equidistant. On giving a sharp tap to one end of the spring, a few turns will come closer together. This state of compression moves forward along the..

Introduction - In the previous chapters we studied the different types of motion like uniform motion, accelerated motion, projectile motion and periodic motion. We then learnt to relate the acceleration of the body to the force applied. In this chapter we shall study the motion of collection of par..
