Question

Calculate the peak-wavelength for the human skin when the temperature of the human skin
is 32°C.
(a) 2x10-8 m
(b) 9.5x10m
(c) 5x10-m
(d) 3x10 m​

Answer 1

Answer:

 

9.5 ×10∧-6 m

Explanation:

Wien's displacement law states that the black-body radiation curve for different temperatures peaks at a wavelength inversely proportional to the temperature.

we get the peak wavelength of radiated light:  

   λ=b/ T

   λ= 9.5×10∧-6m
