Investigating IR Radiation

Question 1

Different surfaces emit different amounts of IR radiation

Answer 1

1) the anount of infared radiation an object gives out depends on the temperature
2)it also depends on its surface
3)this includes how rough or shiny it is, and its colour
4) you can investigate how much IR radiation different surfaces emit using a Leslie cube.
5) a Leslie cube is a hollow,metal cube
6) the four side faces have different surfaces
