Physics

Discovery of electrons

JJ Thomson

Electric charge measured for the first time

Oil drop experiment

Charges that can exist

Only whole numbers

Hottest to coldest temps

Cool colors to hot colors

Black body radiator at short wavelengths problem

Ultraviolet Explosion

Solution to Black body radiator problem

Light comes in packets of energy

Photon with greatest energy

Gamma ray

Photon with least energy

Radio waves

The photoelectric effect

Light is a particle

Kinetic energy of photoelectrons depends on

Photon frequency

Rutherford's Gold Foil experiment caused a modification of

Plum-pudding model of the atom

Rutherford's Gold Foil experiment, properties of atoms

The size of the nucleus is much less than the size of the atom

When electron falls from orbit n=2 to n=1

A photon is emitted

Limitations of Bohr Model of the atom

The model only applies to hydrogen-like atoms

The Compton effect supports theory that

Light is a particle
