Using wien’s law, estimate the wavelength at which these common materials radiate their peak brightness (show your work):

walls at 300 k:

ice water at 273 k :

hot water at 373 k :

skin at 310 k:

an incandescent light bulb at 3000 k

Explanation:

Wien’s Law:

The law states that the wavelength at which black body emits maximum heat  is inversely proportional to the temperature of the body in Kelvins.

1) Walls at 300 K

2) Ice water at 273 K :

3) Hot water at 373 K :

4)Skin at 310 K:

5)An incandescent light bulb at 3000 K
