What is the photon energy of light with a wavelength of 439 nm?

Note that h = 6.626 x 10-34 J-s and c = 3.00 × 108 m/s.

h = 6.626 x 10^-34 J-s = Plancks constant

c = 3.00 × 10^8 m/s = speed of light

energy = Plancks constant x speed of light / wavelength

(6.626 x 10^-34 J-s x 3.00 × 108 m/s / 439 nm
