Recall that the energy of a photon (E) is given by:
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:
c = speed of light (3.0 × 108 m/s)
Carbon absorbs energy at a wavelength of 150 nm. The total amount of energy emitted by a carbon sample is 1.98 x 105 J. Calculate the number of carbon atoms present in the sample, assuming that each atom emits one photon.
