Which of the following photons has the lowest frequency?
A)a photon from a lightbulb with   500 nm
B)a photon from a particle accelerator with   10 nm
C)a photon emitted from a nuclear reaction with   425 nm
D)a photon from an N laser with   337 nm
E)a photon from a KrF eximer laser with   248 nm

Question

Quizplus · Accepted Answer

The frequency of a photon is inversely proportional to its wavelength. Therefore, the photon with the longest wavelength has the lowest frequency. Among the given options, a photon from a lightbulb with a wavelength of 500 nm has the longest wavelength, thus the lowest frequency.

Which of the Following Photons Has the Lowest Frequency
