The temperature of your skin is approximately 35C degrees. What is the wavelength at which the peak occurs in the radiation emitted from your skin?

Answer 1

Use the Wien displacement law.

Lambda(max) * T = -0.3 cm*K

T in this case be in Kelvin, and therefore 308 K.

Solve for Lambda(max), the wavelength with the most emission per unit wavelength

Answer 2

1.39
