Most microwave ovens emit electro-magnetic radiation with a wavelength () of 12.24 cm. This EM-radiation is used to heat stuff up, like food, and it is emitted at a rate of 6.30 × 1026 photons/second for a typical microwave. How long will it take to boil a 175.0 mL cup of water initially at 25.5 ºC (water boils at 100.0 ºC) if 45.0% of the photons emitted by the microwave oven are absorbed by the water? My answer does not even make any sort of rational sense...
