Question:

A 900-W microwave generator in an oven generates energy quanta of frequency 2560 MHz.

(a) How many energy quanta does it emit per second?

(b) How many energy quanta must be absorbed by a pasta dish placed in the radiation cavity to increase its temperature by 45.0 K? Assume that the dish has a mass of 0.5 kg and that its specific heat is 0.9 kcal/kg ∙ K.

(c) Assume that all energy quanta emitted by the generator are absorbed by the pasta dish. How long must we wait until the dish in (b) is ready?
