MECHANICAL WAVES

I. IDENTIFICATION

A disturbance or variation that causes energy to be transferred gradually from one point to another in a medium; it can be an elastic deformation or a change in pressure, electric or magnetic intensity, electric potential, or temperature.

Starts with "W"

Waves that transfer energy from one place to another, but does not necessarily transfer any mass. Light, sound, and was in the ocean are common examples of waves. Sound and water waves are example of...

"M W"

In this type of wave, the movement of the particles is parallel to the motion of the energy, i.e. the displacement of the medium is in the same direction in which the wave is moving Example - Sound Waves, Pressure Waves.

When the movement of the particles is at right angles or perpendicular to the motion of the energy, then this type of wave is known as...

"T W"

In this type, the particles travel in a circular motion. These waves usually occur at interfaces. Waves in the ocean and ripples in a cup of water are examples of such waves.
