Goal and options: ho emuch energy does a photon have

OPTIONS:
- A photon can contain as much energy as you want. All electrons have exactly 1 unit of electric charge, no more, no less. Energy, by contrast, is proportional to frequency: E=hf, where h is the Planck's constant (6.6x10^-34 Joule-seconds).
- A photon can contain as much energy as you want. All electrons have exactly 10 units of electric charge, no more, no less. Energy, by contrast, is proportional to frequency: E=hf, where h is the Planck's constant (6.6x10^-34 Joule-seconds).
output answer: A photon can contain as much energy as you want. All electrons have exactly 1 unit of electric charge, no more, no less. Energy, by contrast, is proportional to frequency: E=hf, where h is the Planck's constant (6.6x10^-34 Joule-seconds).
