Use a computer to calculate Planck's radiation law for a temperature of 3000 K, which is the temperature of a typical tungsten filament in an incandescent light bulb. Plot the intensity versus wavelength. (a) How much of the power is in the visible region (400-700nm) compared with the ultraviolet and infrared? (b) What is the ratio of the intensity at 400 nm and 700 nm to the wavelength with maximum intensity?

A) The emissivity of the human skin is 97.0 percent. Use 35.0 °C for the skin temperature and approximate the human body by a rectangular block with a height of 1.93 m, a width of 38.0 cm and a length of 26.5 cm. Calculate the power emitted by the human body. B) What is the wavelength of the peak in the spectral distribution for this temperature? C) Fortunately our environment radiates too. The human body absorbs this radiation with an...

A certain pot of melting metal is measured to have a temperature of 1808 K. Your skin is measured at 33 °C. Assume both examples radiate like a blackbody. a) Calculate the wavelength does the melting metal radiate at maximum intensity and which region of the electromagnetic spectrum does this wavelength correspond? b) Repeat part a) for your skin.

The illustration shows the
spectrum of electromagnetic radiation emitted by a blackbody at two
different Kelvin temperatures. The range of visible frequencies
(those that can be detected by the human eye) is also shown.(a) No
matter what the value of the Kelvin temperature T, the
spectrum decreases to zero at very high frequencies. Why is
this?(i) At very high frequencies the photon energy is very small
compared to kT.(ii) At very high frequencies the photon
energy is very large compared...
