Physics

The overall condition of motion of a wave at any moment in time is known as its phase.

Intensity is the amount of sound energy flowing per second per unit areas perpendicular to the direction of propagation of sound waves.

Sound is energy. Sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium.

The strain of an elastic object or material is proportional to the stress applied to it. Stress ∞ Strain

The periodic movement transmits energy from one place of a medium to another but the particles of the medium are not displaced permanently, which is called a wave.

A sound or sounds caused by the reflection of sound waves from a distant surface back to the listener is called an echo.

Sound pollution refers to an audibility limit exceeding 20,000 Hz that causes different health-hazards to the listeners.

In science, particularly in physics, the concept of space and time is very important. We need the concept of space and time to describe any event because without it we cannot get a clear idea about space and time of the event. The concept of space is in vogue from ancient times to locate the … Read more
