1.	Kepler space telescope generated a plot of intensity of radiation versus wavelength of three stars in Andromeda galaxy. What is the relation between their temperature?(a) TA > TB > TC(b) TC > TB > TA(c) TA > TC > TB(d) TB > TC > TA
Answer» Answer : (c) T_A > T_C > T_B Wien’s law, λ_m ∝ \(\frac{1}{T}\) And from the figure, (λ_m)_A< (λ_m)_C< (λ_m)_B. Therefore, T_A > T_C > T_B.

Answer»

Answer : (c) T_A > T_C > T_B

Wien’s law,

λ_m ∝ \(\frac{1}{T}\)

And from the figure,

(λ_m)_A< (λ_m)_C< (λ_m)_B.

Therefore,

T_A > T_C > T_B.
