sounds and motions

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 sh..

Summary - WAVE is a form of disturbance, which travels through a material medium due to the repeated periodic motion of the particles of the medium about their position. Mechanical wave is a periodic disturbance, which requires a material medium for its propagation. Electromagnetic wave i..

For example, an excited tuning fork or a plucked guitar string, produces sound. On close observation, the prongs of the tuning fork or the string is found to have a hazy and blurred outline on account of rapid vibrations. If they are gently touched with the fingers, a series of impulses w..

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..

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 w..
