Mechanical waves

​Introduction to waves

​LO: Describe some properties of waves

​What is a wave?

​A wave is a disturbance that transfers energy from one place to another without transferring matter

​1. Wave transfer matter

2.Wave transfer energy

3.Wave transfer energy and matter

4.Energy and not matter

​

​What Mechanical waves?

​Mechanical waves that travels only in matter

1. Mechanical waves travel through solids only

2. Mechanical waves travels through liquids only

3. Mechanical waves travels through gas only

4. Mechanical waves travel through solids, liquids and gases.

​What is a medium?

1.Medium is any _______a wave travels through.

2.Mechanical waves cannot travel through v_____

​Two types of mechanical waves

​Transverse waves and Longitudinal waves

​Transverse wave disturbance is perpendicular to wave direction

Longitudinal wave particles move parallel to the wave direction

​Transverse wave

​Crest

​Trough

​Wave direction

​Longitudinal waves
