Classically, what initial frequency of light would a ground-state hydrogen electron emit?
AAbout 6.6 x 10^15 Hz
BAbout 1.5 x 10^11 Hz
CAbout 3.0 x 10^8 Hz
DAbout 2.2 x 10^6 Hz
Answer & Solution
Correct answer: A. About 6.6 x 10^15 Hz
The revolution frequency v/(2 pi r) with v = 2.2 x 10^6 m/s and r = 5.3 x 10^-11 m is about 6.6 x 10^15 Hz.
