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.

Frequency and wavelength are inversely proportional in a vacuum, following the equation speed = frequency x wavelength. Since the speed of light in a vacuum is constant, knowing the wavelength allows you to determine the frequency of an electromagnetic wave.

If you know the wavelength of an electromagnetic wave in a vacuum you can calculate its?

If you know the wavelength of an electromagnetic wave in a vacuum, you can calculate its frequency using the equation speed = frequency x wavelength, where the speed is the speed of light in a vacuum (approximately 3 x 10^8 m/s). The frequency of an electromagnetic wave is inversely proportional to its wavelength, so as the wavelength decreases, the frequency increases.


If this wave travels at 16 cms it's wavelenght would be?

To calculate the wavelength, you can use the formula: wavelength = speed of wave / frequency. However, to calculate the wavelength, we need to know the frequency of the wave in addition to the speed. If you provide the frequency of the wave, we can calculate the wavelength.


How do you figure out the speed of a wave?

To determine the speed of a wave, you need to know the frequency of the wave and its wavelength. You can calculate the speed of the wave by multiplying the wavelength by the frequency. The formula for the speed of a wave is speed = frequency x wavelength.


How do you get wavelength with amplitude and frequency?

You can calculate the wavelength of a wave by dividing the speed of the wave by its frequency. The speed of a wave is a constant value for a specific medium (e.g. speed of light in a vacuum). So, if you know the frequency, you can find the wavelength using the formula wavelength = speed / frequency. Amplitude, on the other hand, is the maximum displacement of a wave from its equilibrium position and does not directly affect the calculation of wavelength.

If you know the vacuum wavelength of any form of electromagnetic radiation you can determine its frequency because?

the speed of light in a vacuum is constant (c = 3.00 x 10^8 m/s). By using the formula c = λ*f (where c is the speed of light, λ is the wavelength, and f is the frequency), you can calculate the frequency when you know the vacuum wavelength of the electromagnetic radiation.

How do you find wavelength of a wave?

The speed of a wave equals the frequency times the wavelength (speed = frequency x wavelength). Therefore, the wavelength would equal the speed divided by the frequency. Also, the speed of a wave in a vacuum is the speed of light, c, which is a constant.

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.


How do you calculate the amplitude given the frequency and the wavelength?

To calculate the amplitude given the frequency and wavelength, you would need additional information. Amplitude is a measure of the maximum displacement from the equilibrium position in a wave, which requires knowing the wave equation or properties of the medium carrying the wave. Frequency and wavelength alone do not determine the amplitude of a wave.


What is the frequency of a wave with the wavelength of 3m?

To find the frequency of a wave, you can use the equation: frequency (f) = speed of the wave (v) / wavelength (λ). If the wavelength is 3m and you know the speed of the wave (for example, in air at room temperature it is about 343 m/s), you can calculate the frequency using this equation.


What do you need to know to calculate the frequency of a wave?

wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light


What is meant by vacuum wavelength?

Vacuum wavelength is the wavelength that is measured if the wave is passing through a vacuum. To get the wavelength in a medium you need to know the refractive index.
