Determine the power intensity of radiation per unit wavelength emitted at a wavelength of 500.0 nm by a blackbody at a temperature of K.
What value of the energy quantum does it emit?
Assuming that the specific heat capacity of the body is 0.83 kcal/kg⋅K, how many photons must be absorbed to warm the body?
Assuming that all the radiation that the heater emits is absorbed by the body, how much time is required for the body’s temperature to increase?
How many photons were required to vaporize the flesh?
