Earthquake
In I/GCSE Physics, earthquake produce wave motions on the surface and inside the Earth which can be detected by instruments located on the Earth’s surface.
There are two types of shock waves: P – waves and S – waves. Differences in the speed of P – and S- waves can be used to give evidence for the structure of the Earth.
Waves are regular patterns of disturbance that transfer ENERGY in the direction the wave travels without transferring matter- there are two types of LONGITUDINAL and TRANSVERSE.
Waves
LONGITUDINAL WAVE – Each particle moves backwards and forwards in the same plane as the direction of wave movement. Each particle simply vibrates to and from about its normal position stated in I/GCSE Physics.
TRANSVERSE WAVE- Each particle moves up and down at right angles (90˚C) to the direction of wave movement. Each particle simply vibrates up and down about its normal position.
That's all for this chapter. Thanks!
