Visible light falls into wavelength ranges of 400-700 nm, for which 1 m =1 × 10° nm. The energy and wavelength of light are related by the equation hc E = where E is energy in Joules, h is Planck's constant (6.626 × 10-34 J-s), c is the speed of light ( 2.998 × 10° m/s), and A is the wavelength in m. If a visible light photon has a wavelength of 693.7 nm, what is the energy of the photon (in J)?
