Give 3 Examples of infrared Radiation taking place
1) Put your hand near a cup 2)On a sunny days out when you absorbs the suns heat(This is due to the heat travelling through a vacuum by electromagnetic waves). 3) The feeling of Warmth when you but your head next to a fire place

Does Infrared Radiation require particles?
No, it uses electromagnetic waves for heat transfer

8 of 16
How does Infrared Radiation transfer heat?
It travels through a vacuum by electromagnetic waves
9 of 16
Name types of ways in which Heat can be transfered
1)Conduction 2)Convection 3)Condensation 3)Radiation 3)Evaporation

How do you detect heat?
Thorough you skin - you feel the warmth
11 of 16
Suggest a reason why white surfaces emit and absorb less?
Because it reflect light, so less heat is going to go through
12 of 16
Suggest a reason why black surfaces emit and absorb more?
Because it absorb all the wavelength (electromagnetic waves) so it is likely to absorb and also emit more

14 of 16
What are the uses for a theromogram?
Used in hospital to check if a person wounded or it can be used in airport for security reasons
