  13. As noted in class, indigo was added to the rainbow by Newton to generate a seven color rainbow. Looking at a spectrum, however, there really is no visually different color at the position of indigo. If indigo were to be replaced, what color would you add to the rainbow colors, the spectrum, and why?

    1. _________ How many waves are there from the first crest to the fourth crest - the 680 centimeters seen above?
    2. λ = _________ _________ What is the wavelength λ of ONE wave?
    3. a = _________ _________ What is the amplitude a?
    4. τ = _________ _________ What is the period τ of ONE wave?
    5. f = _________ _________ What is the frequency f?
    6. ѵwave = _________ _________ What is the wave velocity ѵwave?

period τ = 1 ÷ (frequency f ) || velocity ѵ = wavelength λ * frequency f
