Problem: How much energy (in kJ) do 3.0 moles of photons, all with a wavelength of 655 nm, contain?

FREE Expert Solution

Recall that the energy of a photon (E) is given by:


E=hv (1)


where:

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

v = frequency (in s–1)


Also, recall that the frequency (v) and wavelength (λ) are related:


λ=cv (2)


where:

c = speed of light (3.0 × 108 m/s)
