Exam 2 March 20

Description of content:

• Radiative heat intensity, power, planck energy density formula and relation to intensity or power, relavance of Boltzmann statistics
  • Other radiative heat gain/loss-NET
• Braking radiation, energy, wavelength, frequency, momentum initial and final,
  • Compton--energy, wavelength, various angles.
• Photoelectric effect data
  • Select appropriate data
  • Determine Planck's constant (without extreme clutter please)
  • Work function (again without clutter)
  • Other data considerations
• Beam of light-absorption-intensity-number of photons

And just for thought

• Did you know you could cook a chicken by slapping it---We are not going to try, but maybe by hitting it with light.
• If you did jump out into deep space, but had a blanket that only let light out in a narrow range of wavelengths at your peak wavelength---(narrow bandpass filter, notch filter, interference filter, ) ---say peak + or - 0.5 nm, what would by your rate of heat loss. Since I've said this is at the peak can you simplify (Lambda*T) ?

This is one problem set-----> Ch. 10 ----1, 5, 6, 13, 14,   AND CH. 11   --1,6,7 , 9, 16-- (Ch. 10 and 11 are one HW)
