Indicate which of the following sources produces the highest energy photons. A) a radio station with $\lambda$ = 106.7 MHz B) a dentist's X-ray source with $\lambda$ = 100 pm C) the laser in a CD player with $\lambda$= 650 nm D) a microwave oven with v= 6.0 * 10¹⁰ Hz E) your cell phone with v = 1.750 GHz

Question

Quizplus · Accepted Answer

The dental X-ray source has the shortest wavelength (highest frequency) out of all the options given, indicating that it produces the highest energy photons. Photon energy is directly proportional to frequency (E = hf), so the source with the highest frequency (shortest wavelength) produces the highest energy photons.
