What is measured in hertz?
- AFrequency
- BEnergy
- CHeat
- DQuality
- ENone of the above / More than one of the above
Show answer and explanation
Correct answer: (a) Frequency
Explanation
Hertz (Hz) is the SI unit of frequency – the number of cycles of a repeating event per second.
It relates to period by the formula f = 1/T.
Energy and heat are measured in joule (J), not hertz, ruling out those options.
