What is the unit for measuring frequency?

Frequency is defined as the number of cycles of a periodic wave that occur in a unit of time. The standard unit for measuring frequency in the International System of Units (SI) is the Hertz, which is equivalent to one cycle per second. This means that if an event occurs once every second, it has a frequency of 1 Hertz.

Understanding frequency is crucial in many areas of physics, particularly in fields such as radiology, where frequency plays a significant role in the behavior of electromagnetic waves, including X-rays and other forms of radiation. Use of the steeper frequency allows for precise measurements and understanding of various physical phenomena.

The other options represent different physical quantities: Joules measure energy, Watts measure power, and Ohms measure electrical resistance. These units do not relate to the concept of frequency, which is why they are not appropriate answers for this question.
