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 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. We at Anand Systems Engineering manufacture Radio remote controls for industrial cranes and we use Frequency to communicate between the transmitter and receiver.
