The wave is amplified electronically and applied to either an oscilloscope ,where the trace is drawn on a calibrated graticule using a known timebase sweep, or it is applied to an electronic timer that counts the time for one complete cycle of the unknown wave and displays the result digitally as Hertz by means of a frequency meter.
What else can I help you with?
Which property of electromagnetic waves is measured in Hertz?
The frequency of electromagnetic waves is measured in Hertz (Hz). Frequency represents the number of wave cycles that pass a given point per unit of time.
Is frequency measured in Hertz?
Yes, frequency is measured in Hertz (Hz). Hertz represents the number of cycles per second of a periodic wave, such as sound or electromagnetic waves.
What is the relationship between the energy of an electromagnetic wave and its frequency?
The energy of an electromagnetic wave is directly proportional to its frequency. This means that as the frequency of the wave increases, so does its energy.
How do you know the speed of an electromagnetic wave in vacuum?
The speed of electromagnetic waves in a vacuum is the same as the speed of light (which is, in itself an electromagnetic wave). It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
How does the wavelength of an electromagnetic wave relate to its frequency?
The wavelength of an electromagnetic wave is inversely proportional to its frequency. This means that as the frequency of the wave increases, its wavelength decreases, and vice versa.
On what does the energy of an electromagnetic wave depend?
The energy of an electromagnetic wave depends on its frequency.
What is the frequency of an electomagnetic wave?
The frequency of an electromagnetic wave is the number of complete cycles of the wave that pass a given point in one second. It is measured in Hertz (Hz), where one hertz equals one cycle per second.
What does the energy of a electromagnetic wave depend on?
The energy of an electromagnetic wave depends on its frequency. The energy is directly proportional to the frequency of the wave, meaning higher frequency waves have more energy.
Is the frequency the same as the speed of the electromagnetic radiation?
No, the two things are quite difference. Frequency means how often a wave goes "up" and "down" - it is measured in cycles/second (hertz). Speed is measured in meters/second. The relationship is: speed = frequency x wavelength This relationship is valid for any wave. In the case of electromagnetic waves, the speed is approximately 300,000,000 m/s.
What determines the frequency of an electromagnetic wave?
The frequency of an electromagnetic wave is determined by the speed of light divided by the wavelength of the wave. This relationship is defined by the equation: frequency = speed of light / wavelength.
What is the frequency of a wave measured by?
The frequency of a wave is measured by counting the number of wave cycles that pass a fixed point in a given time period, usually measured in hertz (Hz). It represents how many times the wave repeats in one second.
What happens to energy of an electromagnetic wave as its frequency increases?
As the frequency of an electromagnetic wave increases, the energy of the wave also increases. This is because the energy of an electromagnetic wave is directly proportional to its frequency, according to Planck's equation (E = hf), where E is energy, h is Planck's constant, and f is frequency.
