Question

1. electromagnetic radiation frequency represents:

the color intensity of light waves
number of waves passing a point per second
total energy of a single wave
distance between wave peaks

Explanation:

The frequency of electromagnetic radiation is defined as the number of waves that pass a given point per second. It is measured in hertz (Hz). Color intensity is related to amplitude, energy of a single - wave is related to frequency but not what frequency represents, and the distance between wave peaks is wavelength.

Answer:

Number of waves passing a point per second
