STANDARD Physics Wien's Displacement Law MCQ Question
Type: MCQ-numerical-Medium-Class 11
Experimental investigations show that the intensity of solar radiation is maximum for a wavelength 480 nm in the visible region. Estimate the surface temperature of sun. (Given Wien's constant b = 2.88 × 10⁻³ m K).
A
4000 K
B
6000 K
C
8000 K
D
10⁶ K
Correct Answer
Option B
Detailed Explanation
According to Wien's displacement law, λₘₐₓT = b where b is the Wien's constant. Substituting the given values, we get T = 2.88 × 10⁻³ m K / 480 × 10⁻⁹ m = 6000 K.
