For the thermal radiation from an ideal blackbody radiator with a surface temperature of 2000 K, let Ic represent the intensity per unit wavelength according to the classical expression for the spectral radiancy and IP represent the corresponding intensity per unit wavelength according to the Planck expression.What is the ratio Ic/IP for a wavelength of (a) 400 nm (at the blue end of the visible spectrum) and (b) 200 mm (in the far infrared)? (c) Does the classical expression agree with the Planck expression in the shorter wavelength range or the longer wavelength range?
How much energy does a photon of UV light (frequency = 3.6 x 1016 Hz) have? How fast do the light travel in a vacuum, water (n=1.33), and glass (n=1.50)?
A satellite in Earth orbit maintains a panel of solar cells of area 2.60 m2 perpendicular to the direction of the Sun’s light rays. The intensity of the light at the panel is 1.39 kW/m2. (a) At what rate does solar energy arrive at the panel? (b) At what rate are solar photons absorbed by the panel? Assume that the solar radiation is monochromatic, with a wavelength of 550 nm, and that all the solar radiation striking the panel is absorbed. (c) How long would it take for a “mole of photons” to be absorbed by the panel?
