Frequency of 5.0 x 10^18 x-ray in nm

Answer 1

To find the frequency of an X-ray with a wavelength of 5.0 x 10^18 nm, we can use the equation:

frequency (Hz) = speed of light (m/s) / wavelength (m)

First, we need to convert the wavelength from nm to meters by dividing it by 10^9:

5.0 x 10^18 nm = 5.0 x 10^9 m

Next, we can use the speed of light in a vacuum, which is approximately 3.00 x 10^8 m/s, to calculate the frequency:

frequency = 3.00 x 10^8 m/s / (5.0 x 10^9 m)
frequency = 6.0 x 10^7 Hz

Therefore, the frequency of an X-ray with a wavelength of 5.0 x 10^18 nm is approximately 6.0 x 10^7 Hz.
