Problem 74

Integrated Concepts A certain heat lamp emits 200 W of mostly IR radiation averaging 1500 nm in wavelength. (a) What is the average photon energy in joules? (b) How many of these photons are required to increase the temperature of a persons shoulder by 2.0C , assuming the affected mass is 4.0 kg with a specific heat of 0.83 kcal/kg C . Also assume no other significant heat transfer. (c) How long does this take?
