Hercio (Hz)

The video tutorial explains the concept of frequency, measured in Hertz, named after Heinrich Hertz. It covers the multiples of Hertz, such as kilohertz and megahertz, and their application in describing electromagnetic radiation frequencies. Additionally, it discusses sound wave frequencies, using a tuning fork with a natural frequency of 440 Hz as an example.

How is the frequency of electromagnetic radiation described?

What is the natural frequency of a tuning fork as mentioned in the text?
