Question

Star x emits maximum radiation of wavelength 4000 and star y emits maximum radiation of wavelength 8000 , then ratio of temperature of two stars is

Answer 1

Hello dear,

◆ Answer-

T1/T2 = 2

◆ Explaination-

# Given-

λmax1 = 4000 A = 4×10^-7 m

λmax2 = 8000 A = 8×10^-7 m

# Solution-

According to Win's displacement law, maximum wavelength of radiation is inversely proprtional to temperature of star.

i.e. λmax ∝ 1/T

Ratio of temperatures -

T1 / T2 = λmax2 / λmax1

T1 / T2 = (8×10^-7) / (4×10^-7)

T1 / T2 = 2

Therefore, ratio of temperature of two stars is 2.

Hope it helps...
