Document Summary
Mon, sept 21: avogadro"s number: 6. 0221409e+23, e = nhv. H =planck"s constant = 6. 626 x 10^-34 j*s v = velocity, frequency (hz, 1/s) N = usually is 1 = quantum number (whole number); vibrational energies of atoms are quantized; intensity. With more intensity, more photons: e = hv. Einstein took it step further to describe light. Light consists of quanta (now called photons) particles of electromagnetic energy. V = frequency of light: e = C = speed of light = 3 x 10^8 m/s. First ta office hours start sun 9/27. Administrative issues: camille bayas (bayas@stanford. edu: overall. Always read lab before because section quiz could ask about the lab. Block out 3-4 hours for homework; work together. Never put name on homework, put code: homework. 3 points if 80% correct for peer review, focus on helpful comments, nothing informal always circle ta"s name: other. Best solar cell gets extra credit: atoms.
