A red photon has a frequency of 650 nm.An ultraviolet photon has a frequency of 250 nm.The energy of an ultraviolet photon is __________ than a red photon.
A) 2.6 times larger
B) 6.8 times larger
C) 2.6 times smaller
D) 6.8 times smaller

Question

Quizplus · Accepted Answer

The energy of a photon is directly proportional to its frequency. Therefore, the energy of an ultraviolet photon is 650 nm / 250 nm = 2.6 times larger than a red photon.

A Red Photon Has a Frequency of 650 Nm
