- 213 Types of wavesMechanical
Electromagnetic
Matter - 22Derive Velocity from y = YSIn(wt + phase shift)v = dy/dt
V = wY SIn(wt + phase shift)
wY = Max Velocity - 23Photo electric effect EquationEk max = hf - work function
- 24Snells LawN1 . Sin 1 = N2 . Sin2
- 25refractive index equationn = C / V
- 26Energy of a PhotonE = hf
- 27List e/m waves in order of frequency (low to high)Radio, Micro, I.R, Visible, U.V, X - ray, Gamma
- 28Wave length of a Harmonicwavelength = 2L / n
- 29General equation for standing Wavey = Ysin(Kx). Sin (wt + phase shift)
- 30Frequency threshold is when...?Ek max = O
so.. hf = work function - 31If light is a wave, what 3 simple predictions could be made about the photoelectric effect?1.) There would be a delay between the moment the electron receives the energy and the time it is ejected.
2.) Ek would be proportional to Intensity
3.) Should occur for any frequency - 32Derive equation for momentum of a photonP = mv = mc
E= mc^2 (m = E/c^2)
P = E/C (E = hf )
P = hf/C C=wavelength x f
P = h/wavelength - 33De Broglie Wave lengthwavelength = h/p = h/mv
