Waves

What is the definition of a wave

a way of transferring energy from one point (source) to another (receiver) with no net transfer of matter

What do waves need to be transmitted

a disturbance, a medium to travel through, and somewhere to receive wave energy

What are the types of waves

Longitudinal, transverse, mechanical waves, EMR waves

What is a longitudinal waves (and example)

particles displaced in same direction as propagation (e.g. sound)

What is a transverse wave (and example)

particles displaced at a right angle to propagation

What is a mechanical wave and example

require particles of matter in medium to oscillate and transfer energy (e.g. sound)

what is an EMR wave and example

Electro magnetic radiation, electric field and magnetic at right angles to each other (always transverse wave) e.g. light
