Demo: Flame emission spectra of iron filings over open flame. flame emission spectra of wooden sticks soaked in different salts to produce different colors. Emission spectra(s) produced by exciting metals into ions using methanol. PHOTO
Demo: Polarizing filter with Karo syrup to produce a negative rainbow show that sugar bends light to the left. We can only see the individual colors of light when the wavelengths are separated into polarized light (all moving in the same direction).
