Start by recalling the formula for the energy of a photon, which is given by: , where is the energy, is Planck's constant, and is the frequency of the light.
Planck's constant is approximately J·s. This is a fundamental constant used in quantum mechanics.
Substitute the given frequency of green light, s-1, into the formula: .
Perform the multiplication of the constants and the frequency. This involves multiplying the numerical values and adding the exponents of 10 according to the rules of exponents.
After calculating, you will obtain the energy of the photon in joules. Compare your result with the given options to identify the correct answer.
