a2 applied science revision

Is a disturbance that propagates through a material medium or space.

In order for a mechanical wave to exist energy is needed to create a disturbance in an elastic medium.

waves transfer energy without the bulk transport of matter.

Types of wave

Longitundinal waves

coils move left and right they also compress and expand.

longitundinal is when The displacement of particles of medium is parralel to the direction of wave propagation.

Tanverse waves

coils move up and down.

transverse is when the displacement of the particle of medium is perpendicular to the direction of wave propagation. 

Waves and charateristic

Amplitude

is the maximum displacment…
