Arrangement of Electrons in Atoms
Light
characteristics
particle-like
wavelike
visible light
Electromagnetic radiation
energy
wavelike behavior
ex) X-rays, ultraviolet, infrared light, microwaves, radio waves
3.00 x 10^8
electromagnetic spectrum
Frequency
number of waves that pass a given point in a specific time (one sec)
One wave/sec -> Hz
wave on the surface of water
related to wavelength
interactions of light
+) it can't be explained by the wave theory of light.
Two experiments to prove this
photoelectric effect
emission of electrons from a metal when light shines on the metal
mystery
quantum of evegy
minimum quantity of energy that can be lost or gained by an atom
E=hv
Planck's theory
Einstein
Einstein expanded on his theory by introducing electromagnetic radiation has a dual wave-particle nature.
