Demonstration of wave generation with a spring. Only certain allowable frequencies produces standing waves. Difficult to produce a high frequency wave - too much energy required.
Looked at color filters of primary colors of light magenta, cyan, yellow Light has constructive interference all colors of light produce white light The primary colors of pigment are red, blue, yellow pigments have destructive interference when all pigments are combined black is formed.
Emission spectra of electrons in a hydrogen atom. Looked at Balmer series (visible spectra of light), Paschen series (infra red), and
Lyman series (ultraviolet light) and related the individual wavelengths of light to the distance the electron fell down to the ground state in a hydrogen atom.
Spectroscopes emission spectra of light from different sources (hydrogen, oxygen, air).
c = f x (lambda)
speed of light = frequency x wavelength
E = h f
energy = Planck's constant x frequency
Demonstration: Polarizing film (Edwin Land and the Polaroid camera)
