The frequency of a given region of the electromagnetic spectrum ranges from 3 * 1016 - 3 * 1019 hertz. Which type of wave is found in this region?

A. x-rays

B. ultraviolet rays

C. infrared waves

D. radio waves

Wavelength = (speed) / (frequency)

Speed of EM radiation = 3 x 10⁸ m/s

Frequency (3 * 10¹⁹ Hz) = = = > wavelength = 0.01 nanometer

Frequency (3 * 10¹⁶ Hz) = = = > wavelength = 10 nanometers

This is the region of X-rays.
