AIPMT PRELIMS 2006 Physics Wien's Displacement Law MCQ Question
Type: MCQ-conceptual-Medium-Class 11
A black body at 1227°C emits radiations with maximum intensity at a wavelength of 5000 Å. If the temperature of the body is increased by 1000°C, the maximum intensity will be observed at:
A
7500 Å
B
1500 Å
C
6000 Å
D
3000 Å
Correct Answer
Option D
Detailed Explanation
According to Wien's displacement law, λ_max is inversely proportional to temperature. Increasing the temperature shifts λ_max to a shorter wavelength.
