## Frequently Asked Questions

What are frequencies exactly?

Frequency, which is measured in hertz (Hz) units, is the rate at which vibrations and oscillations occur. Frequencies are used to determine and differentiate vibrational patterns. So, an atom that is vibrating at a faster rate would be considered a higher frequency than one that is vibrating at a much slower rate.

What is frequency and how to measure frequency?

Frequency, or f, is the number of times an event occurs in a specific length of time. Any repeating event can be measured for frequency. Examples would be the number of visits a website gets in a day or how regularly a customer purchases the same product in one year. Hertz, or Hz, is the unit of measurement applied to frequency.

What does frequencies mean in physics?

Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
