I'm not sure what that 'a' is doing in there. I'll just go with 2.5 x 109 Hz.
Wavelength = speed/frequency = 3 x 108/2.5 x 109 = 12 centimeters or 1.2 x 108 nm.
This is no "X-ray". This is more like the radio waves in your microwave oven that are used to warm the leftover meatloaf for a quick supper.
The formula is speed of light (3x108)=Wavelength in meters times frequency in hertz
wavelength really=5x10-9 so frequency=6x1016 Hertz or cycles per second
X-rays have a wavelength in the range of 0.01 to 10 nanometers. (source: wikipedia)
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, Frequency, or Photon Energy
c = wavelength X frequency, where c is the speed of light, which is 299,792,458 m/s. So you need the wavelength of the photon. Then you divide c/wavelength and the result will be the frequency.
A photon with energy 3.0 x 10-19 J A photon with wavelength 525 nm A photon with frequency 7.6 x 1014 Hz A photon with frequency 2 x 1015 Hz

You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
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.

Divide the speed of light (in meters/second) by the wavelength (in meters). The answer is in Hz (1/second). Divide that answer by a million to get MHz.
The energy per photon is directly proportional to the frequency; the frequency is inversely proportional to the wavelength (since frequency x wavelength = speed of light, which is constant); thus, the energy per photon is inversely proportional to the wavelength.
The energy of a photon is directly proportional to the frequency. Since the frequency is inversely proportional to the wavelength, the energy, too, is inversely proportional to the wavelength.
The energy increases as the frequency increases.The frequency decreases as the wavelength increases.So, the energy decreases as the wavelength increases.
Twice the energy means twice the frequency, and therefore half the wavelength.
the equation f= c/wavelength means that the frequency is equal to the speed of light divided by the wavelength in Meters. e.g. f=2.9998x108 / 350x10-9 ans: 8.57x1014 Hz.
wavelength : wavelength is the distance from crest of one wave to the crest of next frequency : the number of waves that passes a given point in one second energy : the amplitude or intensity of a wave energy and frequency is directly proportional to each other when energy is high frequency is also high wavelength and frequency or energy is inversly proportional to each other when wavelength is high frequency or energy is low
