Question

The wavelength of a particular color of green light is 534 nm.

The energy of this wavelength of light is .... kJ/photon.

Answer 1

Use E = hc / λ

E = energy/photon in J

h = Planks constant = 6.626x10^-34 Js

c = speed of light = 3x10⁸ m/s

λ = wavelength in meters = 534x10^-9 m

Solve for E and then convert to kJ to get your answer.
