MHT CET Physics question
Two bodies A and B having same surfaces areas have emmissivities of 0.01 and 0.49 respectively. The two bodies emit total radiant power at the same rate. The wavelength corresponding to maximum spectral radiancy in the radiation from B shifted from the wavelength corresponding to maximum spectral radiancy in the radiation from A by 1 m. If temperature of A is 5200 K then,
Answer: (B)
Solution
Equal power with equal areas gives , so K K (B is cooler, so the temperatures 26006 K, 10400 K and 2600 K are all too high or too large for a
