To complete the given table for visible light:


E=hv (1)


where:

h = Planck’s constant (6.626 × 10–34 J • s)

v = frequency (in s–1)


λ=cv (2)


where:

c = speed of light (3.0 × 108 m/s)


E=hcλ (3)



    Color            wavelength, nm

Violet              380 – 450 nm

Blue                450 – 495 nm

Green             495 – 570 nm

Yellow             570 – 590 nm

Orange           590 – 620 nm

Red                 620 – 750 nm



a) Find v, E, color of light


λ(vλ)=cv(vλ)ν=cλν=3.00×108ms713.7 nm×10-9 m1 nm

v = 4.203 × 1014 s-1

            


E=(6.626×10-34 J·s)(4.203×1014s-1)
