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.

As frequency increases so does energy , radio waves have least energy, X-rays and gamma rays have the most energy, gamma rays have 10 to power 20 times more energy than radio waves.

So does this explain why many radio control systems feature a red light b/c it has the fastest frequency or is that just to make sure it’s on?

Hello sir, i have a question.. in house mains there are 2 terminals Phase and neutral right, for any electronic device circuit completion is needed to work, That means current flow through phase and go inside device and come through neutral line, But i use a tester to check voltage in neutral pin when table fan is running, but it shows no voltage, why? And if one cycle have both negative and positive current then electronics work in negative also??
Can You please Correlate This with tetanizing frequency= 1/contraction in Hertz?
5:40, 220 V is the rms voltage . In actual case amplitude will goes up to 440V or 400V

Excellent video, I am a warehouse worker. To be paid at a top rate we need to move fast. There is no practical way to accurately measure progress to 100% electronically or manually. Would a certain hz frequency or a variable mhz frequency be possible on a smartphone i could use to help me move more? Thank you much in advance for a potential for a way to potential success. Or if not, i still thank you.
what exactly are the changes that high frequency or low frequency do to the air?

Radio waves change the energy at a particular point in space , radio waves don’t require any medium such as air or water to travel , sound waves change the pressure of air as shown in the video
hey could you clarify something please: you explained the meaning of hertz.. but i felt there is a gap from understanding hertz to understanding a Terahertz(jumping kilo, giga etc) and i just googled Terahertz and they say its another type of wave which hasnt been utlized,... but then how do we have the blue light.. ? im so confused..

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!
@anandsystemsengineering9142
Жыл бұрын
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 .

@@anandsystemsengineering9142 thanks. But just to make things clear using a visual as an example, in this video where you presented the low pitch sound, if we are to find the wave frequency of the diagram you've shown, would it be 1 hz or 1.5 hz?
Should we block our eyes from hearing these high frequencies? I see many videos online and red light therapy pads using noglier requenciees that are put close to the ear. Myfriend told me she had a light therapy pad near her face and her ear was irritated for a day or two.

What about the difference between alternating current of electricity and direct current of electricity? Your explanation of frequency suggests to me that direct current does not have a frequency. Is that correct?
