How to Calculate the Energy of a Photon
Question:
A photon has a frequency of 150 THz. What is the energy of this photon?
Answer:
To calculate the energy of a photon with a frequency of 150 THz, we can use the equation E = hf, where E is energy, h is Planck's constant, and f is frequency.
When a photon has a frequency of 150 THz, we can plug in the values into the equation:
E = (6.626 × 10^-34 J·s) × (150 × 10^12 Hz)
After multiplying the values, we can find the energy of the photon in joules.
Remember, Planck's constant is a fundamental constant in quantum mechanics, and it relates the energy of a photon with its frequency.
