7. Enjoy!

All objects warmer than their surroundings emit Infrared radiation

What spectrum are Infrared waves part of?

Can you find an image of this spectrum?

Find an image to explain that all objects emit and absorb infrared radiation

What do the words emit and absorb mean?

What surfaces make good absorbers and good emitters of infrared radiation?

Hint → Why are car engines painted black?

What is a ‘matt’ surface? Find some examples

Light, shiny surfaces are poor absorbers and poor emitters of infrared radiation.

Find some images to illustrate this.

Search ‘White houses in spain’ for a start! - Why are they painted white?

Light, shiny surfaces are good reflectors of infrared radiation.

Find some images to illustrate this.

For example you could search for ‘foil behind radiators’ ’

To Finish Use Youtube to find a few videos to explain Infrared radiation.

Searching Aqa gcse infrared radiation is a good place to start.
