What is Frequency ? Frequency Explained. What is Hz?

Ғылым және технология

What is frequency ? We see what is Hertz or Hz. What is an electromagnetic wave ? Amplitude , Frequency and wavelength of a wave.
Frequency is the number of waves or events happening in a second.
Everything is dependent on frequency , The Mains Power , the sound and Electronics depend on frequency.We hope you understand how important is frequency. Light, Sound, Electricity depend on frequency. Everything changes if the frequency is changed. We humans measure events with the help of frequency with the unit of Hertz or in short Hz. Named by the scientist Heinrich Hertz. Red, green, and Blue Light are electromagnetic waves.
We count how many of these waves travel through a single point in a second. Lightwave disturbs stability of space to perform work using a positive displacement and negative displacement.
Less number of red light waves traveling in a second and more number of blue light waves are traveling in a second. If 1 wave is traveling in a second then the frequency is equal to 1 Hz. Sound waves are changes in air pressure. humans listen to the frequency at 20 to 20khz.
Mains electricity is 50 Hz or 60 Hz depending on the country. Mains electricity is a single-phase supply which comes to your house. When we apply 3 phase power supply to an ac induction motor and we can change its speed with the help of changing frequency .Videos by Pexel.

And if one cycle have both negative and positive current then electronics work in negative also??

    Hi, would just like to know. when counting the number of frequency using a diagram, do we only count one complete wave or cycle which is equal to 360 degrees? Have seen some people counting the incomplete cycle like for example if wave is made up of 3 complete cycles and an incomplete cycle say just a trough or a crest, they refer to them as 3.5 cycles, which for me seems not appropriate given that frequency refers to the number of cycles completed per second. Hopefully would be able to get your thought on this. Thanks!

    We have to measure from start to finish , then only the concept of frequency arises , as the definition of frequency is “how many times a complete action has happened in 1 second” . 3.5 cycles is not the correct way of thinking in terms of frequency unless 3.5 cycles leads to completion of 1 action from start to finish .
