Sound waves are created by object vibrations and produce pressure waves, for example, a ringing cellphone. As it is disturbed, each molecule just moves away from a resting point but then eventually returns to it.
Because the speed of these sound waves is low. Develop and use a model to compare and contrast how light and sound waves are reflected, refracted, absorbed, diffracted or transmitted through various materials.

Explain that when a sound is made by the leader, the pinna will start a wave (raising and lowering hands), and the other ear parts will continue in turn so that the wave travels from the pinna through all the parts of the ear to the brain. This means that sound waves with high frequencies have short periods, while those with low frequencies have long periods. JEE Main 2022 Question Paper Live Discussion.
Other sets by this creator. Regions of below normal pressure (regions under tension) are called rarefactions or dilations. Lakhmir Singh Class 8 Solutions. We call this back and forth motion a cycle.

This happens simply because the sounds we make cause air particles to hit each other, creating a denser compression that travels through the air, collision by collision. We know that in a sound wave, the combined length of a compression and an adjacent rarefaction is called its wavelength.
