frequency
|
The number of waves per second that passes a given point in space.
|
|
|
what is the equation between freq, wavelength, and speed of light?
|
wavelength x freq = speed of light
|
|
|
electromagnetic spectrum (from highest to lowest freq)
|
gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves, fm radio, shortwave, am radio
|
|
|
Change in Energy equation (also energy of photon)
|
change in energy (or energy) = h x freq; where h is 6.626 x 10^34 Jxs
|
|
|
photoelectric effect
|
refers to the phenomenon in which electros are emitted from the surface of a metal when light strike it.
|
|
|
threshold frequency
|
a frequency where no electrons are emitted by a given metal if it goes below it.
|
|
|
de Broglie's equation
|
wavelength = h / (mv)
