Which statements about the frequency of an electromagnetic wave are accurate?

Question

Multiple select question.

Frequency is measured in hertz.

The frequency of an electromagnetic wave is the same as the frequency of the vibrations of the charge that produces the wave.

The frequency of an electromagnetic wave is the number of wavelengths that pass a point in one second.

Frequency is measured in meters per second or kilometers per minute.

Answer 1

The accurate statements about the frequency of an electromagnetic wave are:

1. Frequency is measured in hertz. (True)
2. The frequency of an electromagnetic wave is the same as the frequency of the vibrations of the charge that produces the wave. (True)
3. The frequency of an electromagnetic wave is the number of wavelengths that pass a point in one second. (True)

The statement "Frequency is measured in meters per second or kilometers per minute." is not accurate. Frequency is specifically measured in hertz (Hz), which represents cycles per second, not in units of distance/time.
