Calculate the energy per mole of photon released by a microwave with a wavelength of 300 mm
Recall that the energy of a photon (E) is given by:
where:
h = Planck’s constant (6.63× 10–34 J • s)
v = frequency (in s–1)
Also, recall that the frequency (v) and wavelength (λ) are related:
where:
c = speed of light (3.0 × 108 m/s)
My microwave operates at a wavelength of 300.0 mm (note units). What is the energy of a mole of photons generated by this microwave? The value of Planck’s constant, h = 6.63 × 10-34 J s.
a. 4.3 kJ
b. 4.3 × 10-5 kJ
c. 330 kJ
d. 3.3 × 10-4 kJ
e. 5.5 × 10-25 kJ
