An ideal spherical blackbody 24.0 cm in diameter is maintained at 225oC by an internal electrical heater and is immersed in a very large open-faced tank of water that is kept boiling by the energy radiated by the sphere. You can neglect any heat transferred by conduction and convection. Consult Table 17.4 as needed.
(a) At what rate, in g/s, is water evaporating from the tank?
(b) If a physics-wise thermopile organism living in the hot water is observing this process, what will it measure for the peak-intensity (i) wavelength and (ii) frequency of the electromagnetic waves emitted by the sphere?
