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

Question

Multiple select question.

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

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

Frequency is measured in hertz.

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

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

3. Frequency is measured in hertz.

The statement "Frequency is measured in meters per second or kilometers per minute" is inaccurate. Frequency is specifically measured in hertz (Hz), which is defined as one cycle per second. Meters per second and kilometers per minute are units of speed or velocity, not frequency.
