Question

the wavelength corresponding to maximum intensity of radiation emitted by a spoke at temperature 2000K is λ, then what is the wavelength corresponding to maximum intensity of radiation at temperature at 3000k​

Answer 1

Explanation:

Wines displacement law is given by

λm T = constant

λm = maximum wavelength radiation

T = temperature of the body

So for two different cases, ie at two different temperatures,

λ1 T1 = λ2 T2

λ2 = λ1 [ T1 / T2 ]

Given, T 1 = 2000 K

T2 = 3000 K

λ1 = λ

∴ λ2 = λ × 2000 / 3000 = 2/3 λ

Thus the wavelength is 2/3 λ !

Answer 2

Explanation:

♣️Wavelength is ⅔..♣️
