Which of the following is the basic SI unit for the frequency of light?
A
joule (J)
B
meter (m)
C
hertz (Hz)
D
second (s)
Verified step by step guidance1
Understand that frequency refers to how many cycles or waves pass a point per unit time.
Recall that the SI unit for frequency is defined as one cycle per second.
Recognize that the unit 'hertz (Hz)' is used to express frequency, where 1 Hz = 1 cycle/second.
Note that joule (J) is a unit of energy, meter (m) is a unit of length, and second (s) is a unit of time, so none of these directly measure frequency.
Conclude that the basic SI unit for frequency of light is hertz (Hz).
