Wavelength = (speed) / (frequency) = (340) / (20,000) = 0.017 meter = 1.7 centimeter
There are several kinds of dipole; the most common is the half-wave dipole. Its total length is fairly close to half the wavelength of the design frequency. The length needs to be adjusted slightly to compensate for the thickness of the elements and for end-effects. If the length is wrong by ten or twenty percent it will alter the feed impedance, but have little effect on the gain.
You do not. A metre is a measure of distance, a kiloHertz is a measure of frequency. The two measure different things and it makes no sense to convert from one to the other without additional information - for example: whether you are talking about electromagnetic waves, or sound waves, or waves in the ocean or whatever.
Frequency = 1/period1/7.5 x 10-3 = 1331/3 Hz = 2/15 KHz
0.48 KHz = 480 HzPeriod = 1/frequency = 1/480 = 0.0020833 second (rounded) = 21/12 milliseconds
300 meters = 1000 kHz. Wavelength in meters / 300 = frequency in megahertz * 1000 = frequency in kilohertz.
"Meters" is not frequency. It's wavelength. If you know the wavelength in meters, divide 300 by it, and the result is the frequency in MHz. If you know the frequency in MHz, divide 300 by it, and the result is the wavelength in meters.
The wavelength of a 1 kHz (1 kilohertz) signal in air is approximately 343 meters. This wavelength can be calculated using the equation: wavelength = speed of sound / frequency.
wavelength = (speed) / (frequency) = (300,000,000) / (1,300,000) = 230.77 meters (rounded)
The shortest AM radio wavelength occurs at the highest frequency in the given range, which is 1600 kHz. To find the wavelength, we can use the formula: wavelength (in meters) = speed of light / frequency. So, the shortest AM wavelength is approximately 187.37 meters.
The speed of a wave is equal to the product of wavelength x frequency. Just convert everything to standard units (wavelength to meters, frequency to hertz), multiply both, and you'll get the result, also in standard units (meters / second).
For any wave, frequency x wavelength = speed (of the wave). In this case, convert the kHz to Hz, then divide the speed of light by this frequency. The speed of light should be in meters/second. The answer will be the wavelength in meters.
The wavelength of a 20 kHz wave is approximately 15 meters in air. Wavelength can be calculated using the formula: wavelength = speed of sound / frequency.
3 Meters ==> 100 MHz 3 Miles ==> 62.137 KHz
The wavelength of a sound wave can be calculated using the formula: wavelength = speed of sound / frequency. The speed of sound in air is approximately 343 meters per second. Therefore, for a frequency of 30 kHz (30,000 Hz), the wavelength would be approximately 11.43 meters.
The wavelength of a 1 KHz frequency signal is approximately 343 meters in air or vacuum. This can be calculated using the speed of sound in air, which is about 343 meters per second at room temperature.
The speed of a wave is equal to the product of wavelength x frequency. Just convert everything to standard units (wavelength to meters, frequency to hertz), multiply both, and you'll get the result, also in standard units (meters / second).
