Question

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

Answer 1

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.

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

im imagining the closer to the globe the faster the melting

Answer 6

actually im not sure if this is thermal radiation .

Answer 7

oo ok interesting thanks

Answer 8

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

Answer 9

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

Answer 10

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

Answer 11

cups of boiled water*

Answer 12

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
