Blackbody Radiation
A 200-W heater emits a \(1.5-\mu \mathrm{m}\) radiation. (a) What value of the energy quantum does it emit? (b) Assuming that the specific heat of a 4.0-kg body is \(0.83 \mathrm{kcal} / \mathrm{kg} \cdot \mathrm{K}\), how many of these photons must be absorbed by the body to increase its temperature by 2 K? (c) How long does the heating process in (b) take, assuming that all radiation emitted by the heater gets absorbed by the body?
