Q1: The sun can be treated as a blackbody at an effective surface temperature of 10,400 R. The sun can be treated as a blackbody. (a) Determine the rate at which infrared radiation energy (0.76-100 um) is emitted by the sun, in Btu/hft. (b) Determine the fraction of the radiant energy emitted by the sun that falls in the visible range. (c) Determine the wavelength at which the emission of radiation from the sun peaks (d) Calculate and plot the...
4. Find the peak wavelength of the blackbody radiation emitted by (a) The Sun (2000 K) (b) The tungsten of a light bulb at 5800 K (c) Find their intensities (radiated power per unit area)
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...
The Earth absorbs energy emitted from the sun. If the sun emits energy at a rate such that the emitted power is 3.9x1026W how much power is incident on the earth? (Hint, you may need to look up the Earth-Sun distance and radius of the Earth.)

33.2 The electromagnetic radiation emitted from the Sun is most intense at around 502 nm. (a) What is the energy per photon (in J) for light of this wave- length? (b) What is the energy per photon in electron volts? (c) What is the momentum per photon? (d) How fast would an electron (melectron 9.1 x 1031 kg) need to be traveling to have the same momentum as this photon? (e) What would the de Broglie wavelength of such an...
Calculate the average power that the surface of Earth facing the Sun receives from the Sun. Assuming that the Earth is a blackbody and radiates the same amount of power that it absorbs from the Sun, calculate the average surface temperature of the Earth. Does your answer make sense compared to your experience? The Sun’s surface temperature is 5800 K, its radius is 6.96x108 m, the distance between Earth and the Sun is 1.5x1011 m, and the radius of the...
