AP EAMCET · PHYSICS · Thermal Properties of Matter
If the wavelengths of maximum intensity of radiation emitted by two black bodies \(A\) and \(B\) are \(0.5 \mu \mathrm{~m}\) and 0.1 mm respectively, then ratio of the temperatures of the bodies A and B is
- A 5
- B 25
- C 100
- D 200
Answer & Solution
Correct Answer
(D) 200
Step-by-step Solution
Detailed explanation
\(\frac{T_A}{T_B} = \frac{\lambda_B}{\lambda_A}\) \(\frac{T_A}{T_B} = \frac{0.1 \text{ mm}}{0.5 \mu \text{m}}\) \(\frac{T_A}{T_B} = \frac{0.1 \times 10^3 \mu \text{m}}{0.5 \mu \text{m}}\) \(\frac{T_A}{T_B} = \frac{100}{0.5} = 200\)
