Assume the mostly infrared radiation from a heat lamp acts like a continuous wave with wavelength 1.50 µm . If the lamp’s 200-W output is focused on a person’s shoulder, over a circular area 25.0 cm in diameter, then how long will it take to increase the temperature of the 4.00-kg shoulder by 2.00°C, assuming no other heat transfer and given that its specific heat is 3.47 × 103 J/kg. °C ?
