Question

The burner on a stove is 325° f. given that the burner emits electromagnetic radiation as a blackbody, what is the maximum wavelength of the emitted light spectrum?

Answer 1

To solve this, we use the Wien's Displacement Law as shown in the attached picture. First, convert the temperature to Kelvin. 

C to F:
C = (F - 32)*5/9
C = (325 - 32)*5/9 = 162.78 °C

C to K:
K = C + 273
K = 162.78 + 273 = 435.78 K

λmax = 2898/435.78 = 6.65 μm
