What is meant by 'progressive' wave?
A moving wave
1 of 10
What is its purpose?
To carry energy without carrying material
2 of 10
What is the cause of waves?
When something cause particles or fields to oscillate at a source
3 of 10
List two ways that we can tell waves carry energy
Electromagnetic waves transfer heat to objects, X-ray and Gamma rays cause ionising radiation which can knock electrons out of orbit
4 of 10
What do waves tranfer energy through?
Mediums
5 of 10
List another two ways that we can tell waves carry energy
Loud noises cause air oscillations which can make things vibrate, Wave power can be used to generate electricity
6 of 10
Name three way in which a wave can be affected
Reflection, Diffraction, Refraction
7 of 10
Give a brief definition for Reflection
A wave is reflected (or bounces back to the source) at a boundary
8 of 10
Give a brief definition of Diffraction
When a wave passes through a gap, causing it to spread out
9 of 10
Give a brief definition of Refraction
When a wave changes direction as it enters a different medium
