Schrödinger Equation
... Photoelectric Effect • Each metal has a minimum energy needed for an electron to be emitted. • This is known as the work function, W. • So, for an electron to be emitted, the energy of the photon, hf, must be greater than the work function, W. • The excess energy is the kinetic energy, E of the emi ...

Waves and Energy
... Note that because only certain atomic energies are possible, only certain frequencies of radiation can be emitted. You can compare hydrogen's seven atomic orbits to seven rungs on a ladder. A person can climb up or down the ladder only from rung to rung. Similarly, the hydrogen atom's electron ...

CHAPTER 2: Special Theory of Relativity
... The longer path causes a time delay for a light pulse traveling close to the sun. This effect was measured by sending a radar wave to Venus, where it was reflected back to Earth. The position of Venus had to be in the “superior conjunction” position on the other side of the sun from the Earth. The s ...
