Electromagnetic radiation, which includes light and x-rays, travels at 299,792,458 metres per second
(c - a universal constant).
Speed, frequency and wavelength are related by the equation speed = frequency times wavelength.
The only problem with this question is that a frequency of 2.01018 Hz is not in the x-ray range
of frequencies. X-rays are found in the frequency range of 30 petaHertz to 30 exaHertz.
To put it another way, electromagnetic radiation with a frequency of 2.01018 Hz
has a wavelength of 149,137 kilometers (92,669 miles), and that's no X-ray.
A light ray is a straight line with speed c=fw. The speed c is a constant and the product of the wavelength, w and the frequency f. The frequency is f=c/w, inverse to the wavelength. If the wavelength is long the frequency is low; if the wavelength is small the frequency is high.
The wavelength of an X-ray is much shorter than the wavelength of a red light from a neon sign. The frequency is much longer in an X-ray than the frequency of a red light from a neon sign.
Less wavelength implies more frequency. The product of wavelength x frequency is always the speed of the wave - in this case, the speed of light.
x-ray
Increasing the frequency of any electromagnetic wave ... or of any wave for that matter ... decreases its wavelength.
Wavelength = (speed) / (frequency) = 299,000,000 / 5 = 59,800,000 meters = about 37,000 milesThis is no X-ray. It's a longer wavelength (lower frequency) than any electrical signal we generatefor any purpose.The longest wavelength that's called an X-ray is in the neighborhood of 0.00000001 meter.Its frequency is 30,000,000,000,000,000 Hz.
. Longer, and a period that is longer
If you divide the speed of light (in meters/second) by the frequency (in Hz), you get the wavelength (in meters).
The frequency of the laser in the alcohol will be 680nm and the speed of light as always, is 299,792,458 meters per second. Why did you need to ask this?
An X-ray is a high frequency (high energy) electromagnetic wave. It is much higher in frequency than any broadcast wave. The only electromagnetic radiation with higher frequency (shorter wavelength) than the X-ray is the gamma ray.
For the frequency, first convert the wavelength to meters (divide the number of Angstroms by 1010), then use the formula: wavelength x frequency = speed. Using the speed of light in this case. Solving for frequency: frequency = speed / wavelength. To get the photon's energy, multiply the frequency times Planck's constant, which is 6.63 x 10-34 (joules times seconds).
Wavelength. The shorter the wave (= the higher the frequency) the greater the penetration.
