A heat lamp emits infrared radiation whose rms electric field is Erms=3900 N/C. (a) What is the average intensity of the radiation? (b) The radiation is focused on a person's leg over a circular area of radius 3.3 cm. What is the average power delivered to the leg? (c) The portion of the leg being irradiated has a mass of 0.35 kg and a specific heat capacity of 3500 J/kg−C. How long does it take to raise its temperature by 1.8C ? Assume that there is no other heat transfer into or out of the portion of the leg being heated. (a) Number Units (b) Number Units (c) Number Urits
