A black body at 1227°C emits radiations with maximum intensity at a wavelength of 5000Å. If the temperature of the body is increased by 1000°C, the maximum intensity will be observed at
-
- 5000 Å
- 6000 Å
- 3000 Å
- 4000 Å
Correct Option: C
Applying Wein's displacement law,
λmT = constant
5000 Å × (1227 + 273) = (2227 + 273) × λm
| λm = | = 3000 A | |
| 1000 |
