Final answer:
The energy of an ultraviolet photon with a frequency of 7.50 x 10^14 Hz is calculated using the formula E = hf, resulting in an energy of 4.9695 x 10^-19 J.
Step-by-step explanation:
To calculate the energy of an ultraviolet photon with a frequency of 7.50 x 10^14 Hz, you can use the energy equation for a photon E = hf, where E is energy, h is Planck's constant, and f is frequency. Planck's constant h approximately equals 6.626 x 10^-34 J.s.
Substituting into the equation we get:
E = (6.626 x 10^-34 J.s) (7.50 x 10^14 Hz) = 4.9695 x 10^-19 J
