Match the colors of the visible spectrum to their wavelengths.

Note

415 nm = 0.415 μm = 4.15 x 10–1 μm = 4.15 x 10–7 m

Another way to look at this quantity is that 415 nm is about 1/20 the diameter of a red blood cell, a concept that is important for an understanding of how light microscopes work.

415 nm = violet 467 nm = blue 532 nm = green 577 nm = yellow

607 nm = orange 682 nm = red 400 nm (extra knowlege) = violet 700 nm (extra knowlege) = red

Place these photons in the correct order, from lowest to highest energy.

lowest energy = ultraviolet light higher energy = X-rays highest energy = gamma rays

Place the wavelengths of these photons from shortest to longest (remember that shorter wavelengths have higher energy and longer wavelengths have lower energy).
