What is the wavelength if it broadcast at 810 kHz?
The wavelength of a radio wave can be calculated using the formula ( \text{Wavelength} = \frac{c}{f} ), where ( c ) is the speed of light (approximately ( 3 \times 10^8 ) meters per second) and ( f ) is the frequency in hertz. For a broadcast frequency of 810 kHz (or ( 810,000 ) Hz), the wavelength is ( \frac{3 \times 10^8 , \text{m/s}}{810,000 , \text{Hz}} \approx 370.37 ) meters. Thus, the wavelength of a broadcast at 810 kHz is approximately 370.4 meters.
What is the wavelength in feet of a 20 KHz sound wave traveling at 340 meters per second?
Wavelength = (speed) / (frequency) = (340) / (20,000) = 0.017 meter = 1.7 centimeter
What length of dipole in relation to its wavelength in meters or khz?
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.
How do you convert meters to KHz and what is 300 meters in KHz?
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.
What is the frequency in Hz and kHz if the period of oscillation is 7.5 ms?
Frequency = 1/period1/7.5 x 10-3 = 1331/3 Hz = 2/15 KHz
What is 300 meters in KHz. And what formula does the conversion?
300 meters = 1000 kHz. Wavelength in meters / 300 = frequency in megahertz * 1000 = frequency in kilohertz.
How do you convert frequency from meters to megahertz?
"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.
What is the wavelength of 1 kHz?
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.
What is the wavelength of 1290 khz?
wavelength = (speed) / (frequency) = (300,000,000) / (1,300,000) = 230.77 meters (rounded)
AM radio signals are broadcast at frequencies between 550 kHz and 1600 kHz and travel 2.99792 x 108 ms What is the shortest AM wavelength?
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.
What is the speed of a wave with a wavelength of cm and a frequency of KHz?
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).
What is the frequency of this am radio wave in hertz when An AM radio station broadcasts news at 687 kHz?
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.
What is the wavelength of 20kHz?
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.
What is frequency of radio wavelength of 3M?
3 Meters ==> 100 MHz 3 Miles ==> 62.137 KHz
What is the wavelength of a wood with 30kHz frequency?
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.
What is the wavelength if it broadcast at 810 kHz?
The wavelength of a radio wave can be calculated using the formula ( \text{Wavelength} = \frac{c}{f} ), where ( c ) is the speed of light (approximately ( 3 \times 10^8 ) meters per second) and ( f ) is the frequency in hertz. For a broadcast frequency of 810 kHz (or ( 810,000 ) Hz), the wavelength is ( \frac{3 \times 10^8 , \text{m/s}}{810,000 , \text{Hz}} \approx 370.37 ) meters. Thus, the wavelength of a broadcast at 810 kHz is approximately 370.4 meters.
What is the wavelength of 1KHz?
Wavelength = (speed) / (frequency) If this is a 1 KHz sound wave in air, speed = approx 343 meters/sec Sound wavelength = (343 / 1,000) = 0.343 meter = 34.3 cm If this is a 1 KHz radio wave, speed = approx 300,000,000 meters/sec E & M wavelength = (300,000,000 / 1,000) = 300 Km
