The absorption and re-radiation from solid and liquid objects

 

We have to design our own comparison experiment, to find out how different substances absorb or reradiate heat(or light). We do not have to do the experiement.

Suggested equipement: A heat or light source, a bar heater or an overhead projector, a heat detector, your choice of solids and liquids.

 

 

Any ideas, just need ideas

What ideas do you have? Tell us what you think, and we'll suggest improvements or corrections, if required.

I have attempted to research this, with no luck

i need ideas to get me started

You are being asked to design a rudimentary version of a UV/Vis (from the suggestion of an OHP) spectrometer.

Building on what JoeMK said, I think he would prefer a experimental setup,

like How could we measure and identify weather a substance is re-radiating or not?

The prac set up isnt really the prob. The prob i have is the substances that i could test. i seem to have no luck finding these substances. Can someone suggest some that i could test?
