A red photon has a wavelength of 650 nm.An ultraviolet photon has a wavelength of 250 nm.The energy of an ultraviolet photon is ________ the energy of a red photon.
A) 2.6 times larger than
B) 6.8 times larger than
C) 2.6 times smaller than
D) 6.8 times smaller than
E) the same as

Question

Quizplus · Accepted Answer

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

A Red Photon Has a Wavelength of 650 Nm
