Exam-style question
Try this first
A photon has a frequency of 5 x 10^14 Hz. Calculate the energy of this photon using the equation E = hf, where h is Planck's constant (6.63 x 10^-34 J·s).
Model answer
What a good answer should say
- The energy of the photon is 3.315 x 10^-19 J.
Explanation
Why this works
This question tests the understanding of the relationship between frequency and energy of a photon using the formula E = hf. The substitution and calculation demonstrate how to derive the energy from the given frequency.
