Estimate the temperature at which a body may appear blue or red. The values of λ mean for these are 5000 Å and 7500Å respectively. [ Given Wein’s constant b = 0.3 cm K]
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(6 x 10 3 K; 4 x 10 3 K)
λ blue = 5000 Aº
λ m × T = constant = b
λ Red = 7500 Aº
T blue = 
= 
= 6 × 10 3 K
T red = 
= 4 × 10 3 K
