Question

6) Calculate the wavelength of maximum emission for the Earth using Wien’s Law and report the value below. Units are a must. (2 points)

λmax Earth=

Answer 1

The maximum wavelength of earth is 10.097 µm

Step-by-step explanation:

We know that Wien’s Law given as

λmax = 2898/T µm K

If we assume that the average temperature of earth is 14°C.

T= 14°C

T= 14 +273 = 287 K

So

λmax = 2898/T µm K

λmax = 2898/287 µm K

λmax = 10.097 µm

The maximum wavelength of earth is 10.097 µm
