Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
Radio.
No. The radio was invented by Guglielmo Marconi.
The antenna was invented by Heinrich Hertz in 1888. Hertz was a physicist from Germany. Hertz pioneered research into electromagnetism and was considered to be the leading authority on this subject
bites is units for memory, hertz is units for frequency
Heinrich Hertz, German physicist, in 1886.
Audible sound is the sound which is between 20 Hertz to 20000 Hertz and can be heard by human beings, whereas Inaudible sound may be below 20 Hertz or above 20000 Hertz and this can't be heard by human beings.
Frequency is determined by the supply voltage, not by the load. However, for reactive loads (inductors or capacitors), the reactance will vary according to the frequency applied.
Do you mean 'Who made the first radio?'? Several people were experimenting with radio transmission, among them Marconi and Hertz.
Marconi created the first radio in the year 1879. Other personalities have also contributed in the development of radio such as Augusto Righi and Heinrich Hertz.
Hertz measures frequency, the number of cycles per second in a waveform, while decibel measures the intensity or power level of a sound signal. Hertz is a unit of measurement for frequency, typically used in sound waves and electronics, while decibel is a unit of measurement for the amplitude or volume of sound, often used to describe the loudness of a sound signal.
In 1888 Heinrich Hertz created a spark gap transmitter and a receiver sporting a loop antenna.
Frequency is rate at which something is happening whereas amplitude is the strength of a wave, if that wave is traversing a distance of 5 mts in 2 seconds its frequency is 2.5 Hertz. Hertz means per second
