Description

Calculate the temperature of the object that emits blackbody radiation with the following peak

wavelengths:

(a) 1.5 mm (1 m = 103 mm)

(b) 3.1 µm (1 m = 106 µm)

(c) 5.4 nm (1 m = 109 nm)

Explanation & Answer

Using Wien's displacement law :  max. wavelength * T = b (Wein's displacement constant = 2.898*10^-3  m.K)

therefore, T = b / max. wavelength , where T (K), wavelength (m)

a) T = 2.898*10^-3 /  1.5*10^-3   =  1.93 K

b) T = 2.898*10^-3 / 3.1*10^-6 =  934.8 K

c) T = 2.898*10^-3 / 5.4*10^-9 = 536,666.7 K
