distance from the baseline to the crest (depends on the intensity or brightness of the light)
-composed of electric and magnetic field traveling together
-the strengths of the electric and magnetic fields are constantly changing
-wavelength of light waves
Speed of Light (If Consistent)
Wavelength and Frequency are Inversely Related
-the longer the wavelength, the lower the frequency
-the shorter the wavelength, the higher the frequency
Infrared, ROYGBIV, Ultraviolet
Longer Wavelength→Shorter Wavelength
Lower Frequency→Higher Frequency
Diffraction and Interference... light undergoes diffraction and interference... therefore light has as wave nature
the bending of waves through a small opening; a straight beam of parallel waves emerges as a rounded pattern that spreads out
an effect that results when two series of waves merge into each other: constructive and destructive
Planck's Equation for Energy Contained in a Photon
-energy in a photon is proportional to the frequency
Bohr's Model of the Atom
-adds energy levels for electrons
-his model perfectly explains all the lines in his atomic spectra
De Broglie Differs from Bohr's
De Broglie→ light as a wavelength
Bohr→ thought of the electron just as a particle
Davisson and Germer
shoot a beam of electrons through a crystal and obtain a diffraction pattern
-verified light as a wavelength
Quantum Mechanics vs. Newtonian Mechanics
quantum mechanics: very small objects, near speed of light
newtonian mechanic: regular sized objects, normal speeds
derived a wave equation which allows us to calculate the probability of finding an electron
