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.
