What is Frequency and Wavelength of a Ray?

Compute the wavelength of an X-ray with a frequency of 1 1018 Hz. nm?

  • Answer:

    your question has a problem. or two. Just what is a "frequency of 1 1018 Hz nm"? Frequency is in Hz, NOT in nm. And what does "1 1018" mean. And that is NOT an X-ray with a frequency of (guessing) 11018 Hz. But the formula is: λf = c = 2.998e8 m/s (speed of light in vacuum) λ = Wavelength in meters f = frequency in Hz

Wavelength (Lambda) equals the speed of the wave (c) divided by the frequency (f) Lambda=3*10^8 / 1*10^18 = 3*10^-10 m 1 nm = 1*10^-9 Lambda= 0.3 nm

λ = c/f = 3E8/1E18 = 0.30 nm
