If an electron vibrates up and down 1000 times each second, it generates an electromagnetic wave having a
A)period of 1000 s.
B)speed of 1000 m/s.
C)wavelength of 1000 m.
D)frequency of 1000 Hz.
E)wavelength of 1000 km.

Question

Quizplus · Accepted Answer

The frequency of an electromagnetic wave is directly proportional to the frequency of the vibrating electron. Thus, if the electron vibrates up and down 1000 times each second, the electromagnetic wave it generates will also have a frequency of 1000 Hz.
