To solve for the energy of light, we can use the formula E = hf, where E is the energy, h is Planck's constant, and f is the frequency. Plugging in the given values, we get E = (6.626 x 10^-34 J*s)(4.3 x 10^14 s^-1) = 2.85 x 10^-19 J. This is the energy of one photon of light with a frequency of 4.3 x 10^14 s^-1. To find the total energy of a beam of light, we would need to multiply this value by the number of photons in the beam. I hope this helps in solving the formula for the energy of light.
