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) .
Wavelength of red light in a vacuum?
around 750 nanometers.
What would be the wavelength if the violet ray passes through diamond?
The wavelength of a violet ray in vacuum is 400nm. The refractive index of diamond is about 2.42. Using the formula λ'=λ/n where λ' is the wavelength of the ray in a material, λ is the wavelength in vacuum and n is the refractive index of the material, we get λ'=165nm.
An electromagnetic wave in a vacuum has a wavelength of 0.032 m What is its frequency?
Just divide the speed of light (300,000,000 meters/second) by the wavelength.
What is the frequency of light in fused quartz if the wavelength in vacuum is 500nm?
Divide the speed of light in a vacuum (in meters/second) by the wavelength (which you must convert to meters); that will give you the frequency in hertz. The frequency will be the same for different substances.
A microwave and an x ray are traveling in a vacuum compared to the wavelength and frequency of the microwave the x ray has a wavelength that is shorter or longer?
. Longer, and a period that is longer
The wavelength of light is defined as?
The speed of light in vacuum is 299 792 458 Metre_per_second
What is the wavelength of an electromagnetic wave that has a frequency of 2.45 109 Hz in a vacuum (The speed of light in a vacuum is 3.00 108 ms.)?
You need to divide the speed of light (in m/s) by the frequency (in Hz, which is equal to 1/s) to get the wavelength (in meters).
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.
What is meant by homowavelength?
homowavelength crosstalk is a crosstalk that occur on a single wavelength.
What is the frequency of an electromagnetic wave that has a wavelength of 7.6 x m in a vacuum?
3.95*10^13
What happens to the wavelength when you increase the rate of vibration?
Wavelength and frequency have an inverse relationship. c = lambda x f, so f = c/lambda, where lambda is wavelength, f is frequency, and c is the speed of light in a vacuum. Therefore, when the frequency increases, the wavelength shortens.
