any idea of any experiment that can be done for thermal radiation which can be done easily at home ( or even the harder ones) thanks

Question

anonymous · Answer

well. you will need a radiation sensor and a good optical source like a stfan-boltzmann lamp. then again to get an output u need a voltmeter.

disconnect the rotation tray of a microwave oven ,
put plate of frozen water (ice) on in the microwave, observe the melting pattern

anonymous · Answer

UnkleRhaukus what do mean by observing the pattern? can u have further explanation

unklerhaukus · Answer

well a microwave oven works by radiating items with photons of the right energy to excite $H_2O$ molecules 

i would be interested to see how evenly the microwaves are distributed

unklerhaukus · Answer

im imagining the closer to the globe the faster the melting

unklerhaukus · Answer

actually im not sure if this is thermal radiation .

anonymous · Answer

oo ok interesting thanks

anonymous · Answer

any more idea of expereiment on heat transfer  ( conduction or conection or even radiation)

anonymous · Answer

actually i am doing a project i am thinking if radiation is absorbed means conduction and reflection means insulation why now direct do radiation and i can solve all the stuffs

unklerhaukus · Answer

put a two thermometers in  identical (except for colour) black and white cups , 
observe which cools faster

unklerhaukus · Answer

cups of boiled water*

anonymous · Answer

but you are saying about the micorwave after thinking for some moment i think ( i mean my opinion) is that the ice will sublime no mroe pattern to see cause it will direct become gas
