P6:Waves

Question 1

Waves can be…

Answer 1

Absorbed, transmitted or reflected

Question 2

The wave is absorbed by the second material…

Answer 2

The wave transfers energy to the materials energy stores. Often, the energy is transferred to thermal energy store, which leads to heating
E.G:
Microwaves

Question 3

The wave is transmitted through the second material…

Answer 3

The wave carries on travelling through the new material. This often leads to refraction
E.G:
Lenses of glasses and cameras

Question 4

The waste is reflected…

Answer 4

This is where the incoming ray is neither absorbed or transmitted, but instead is ‘sent back’ away from the second material
E.G:
An echo
