Final answer:
The frequency of light can be calculated using the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the light.
Step-by-step explanation:
The frequency of light can be calculated using the equation E = hf, where E is the energy of the photon, h is Planck's constant (6.626 × 10^-34 J·s), and f is the frequency of the light. Rearranging the equation, we can solve for f: f = E/h. Plugging in the given energy for a mole of photons (1.55 × 10^13 J) and Planck's constant, we get: f = (1.55 × 10^13 J)/(6.626 × 10^-34 J·s).
Calculating this, we find that the frequency of light is approximately 2.34 × 10^46 Hz.
