How do you calculate the speed of a radio wave if you know the wavelenghth and frequency?
The speed of every radio wave is 186,282 miles (299,792,458 meters) per second. When you multiply the frequency times the wavelength, that's the result. If it isn't, then you made a mistake somewhere.
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.
Is gamma rays the shortest electromagnetic wave?
There is no shortest electromagnetic wave. The higher the energy the higher the frequency, the shorter the wavelength. But since the definition of gamma rays "Energy of 100-200 kiloElectronvolt and above" has no upper limit, no matter how short the wave is, it will still be called "gamma ray"
Can visible light travel faster in a vacuum than both xrays and radio waves?
No. We call it the "speed of light", but it's also the speed of radio, X-rays, heat, ultraviolet, microwave, gamma rays, etc, and all forms of electromagnetic radiation travel at the same speed, as long as they're in the same medium (vacuum or material substance).
How is volleyball related to math?
Volleyball is related to math. You can calculate the balls weight and distance and speed to calculate how hard to hit the volleyball. Or you can calculate the area of the court your playing on. Another way math is related to volleyball is, when your volleyball goes flat, you'll need to know how much air to pump in it. Volleyball is related to math.
If you know the vacuum wavelength of any form of electromagnetic radiation you can determine its frequency because?
You know its speed in vacuum, and frequency = (speed) / (wavelength) .
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.

What was your average spped for waves with 1-hz frequency?
The speed of a wave does not depend on its frequency. We would only need to know what kind of a wave it was ... whether sound, earthquake, ocean, electromagnetic, etc. ... and what substance it was moving through at the time, and we could either calculate or look up its speed, without ever knowing its frequency.
If you know the wavelength of an electromagnetic wave in a vacuum you can calculate its?
Momentum, energy, frequency, and wave number (but not wave vector.)
How do you find wave length and speed when none is given but frequency is given?
Well, do you know what kind of wave they're talking about ? I mean, is it sound ? Is it electromagnetic, like light or radio ? If it's one of those, then you know the speed, and with speed and frequency, you can calculate wavelength. If it's just a question on a piece of paper that says "There's a wave and it has this frequency, what is it's speed ?", then no answer is possible ... you have one measly piece of information and everything else is unknown.
How do you calculate the frequency of light emitted in chemicals?
There are several ways to calculate the frequency of light emitted or absorbed by different chemicals, and they depend on what you already know. For example, if you know the energy of the particle, then you can calculate frequency from E = planck's constant x frequency and solve for frequency. If you happen to know the wavelength, then you can use C = wavelength x frequency and solve for frequency (where C = speed of light).
What will be the speed when amplitude and frequency is given?
In order to calculate the speed of a wave, you need to know the frequency and wavelength. Amplitude has no effect on the speed, so knowing the amplitude doesn't help.
How do you find velocity when only the frequency is given?
The question is incomplete. Frequency of what? If it refers to electromagnetic waves, you won't need even frequency to determine velocity (in a vacuum), because it will always be c (the speed of light). You can compute the speed of other kinds of waves if you know the frequency and wavelength, but not from frequency alone. The formula is frequency x wavelength = velocity If the waves are electromagnetic, and you have only frequency, you can compute the wavelength using the same formula.
Why is wavelength all you need to know to calculate EM wave frequency in a vacuum?
Because the speed of light in a vacuum is constant(c). hence the formula, v=f.w, where v is velovity, f is frequency and w is wavelength, can be used to calculate the frequency.
How do you calculate the wavelenght of a photon?
You need to know speed and frequency. The speed of all photons is the speed of light, 3.0 x 108m/s. The equation for finding wavelength when frequency and speed are known is λ = ƒ/c , where c is the speed of light, f is the frequency in Hz, and λ (Greek letter lambda) is the wavelength in meters.
