Answer 1

Explanation:

Sound is a form of energy that produces sensation of hearing. We can also say that it is a form of energy and it comes from vibrations. These vibrations create sound waves which move through medium such as air and water before reaching our ears. All sounds are a combination of pure frequencies. A stretched rubber band when plucked, vibrates and produces sound. We have also heard a variety of sounds from sitar, violin, veena, ringing of temple bells, chirping of birds, vehicles honking in traffic, dogs barking, pressure cooker whistling, crackers bursting, rattling and breaking of objects. Also, we hear our favourite song playing in the iPod. While some of these sounds may be pleasant and soothing, some could be annoying. But all these are known as sounds.Types of Sounds

Sound is a kind of wave

Wave is defined as a periodic disturbance in a medium (air, water, and gas) that transfers energy from one particle to another.

When we throw a stone in any water body, like pond or lake, we see ripples and this stone hinders the particles of water due to which disturbances occur in a wide range at a regular interval of time.
