What is the energy of a mole of photons that have a wavelength of 745 nm? (h = 6.626 × 10⁻³⁴ J • s and c = 3.00 × 10⁸ m/s)

What is the wavelength of a photon if the energy is 7.03 × 10⁻¹⁹ J? (h = 6.626 × 10⁻³⁴ J • s)


Sagot :

Answer:The energy carried by a single photon of 535 nm light is 3.71 × 10−19 J.

The equation used to find the energy in a mole of photons is E= hc/lambda where h is Planck's constant, c is the speed of light and is the wavelength of light.
