sound waves from space

Space Waves - Space waves travel in (more or less) straight lines. But they depend on line-of-sight conditions. So, they are limited in their propagation by the curvature of the Earth, except in very unusual circumstances. Thus, they propagate very much like ..

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 en..

Sound is the form of energy propagated as waves which our ears receive. When we speak, our vocal cords vibrate. When we play a guitar, the spring on it makes to and fro motion and produces 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. Human voice originate..

All the effects so far described hold true for microwave frequencies, but some are increased, and new ones are added. Atmospheric absorption and the effects of precipitation must be taken into account. So must the fact that at such short wavelengths, everything tends to happen very rapidly. Refrac..

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. Electromagne..

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..
