The wavelength of X-rays is
Correct answer: A. 10-10
- A. 10-10
- B. 10-8
- C. 10-4
- D. 10-12
Explanation
The value for the wavelength of X-rays is 10-10 corresponding to frequencies in the range of 30 petahertz (PHz) to 30 exahertz (EHz). It is calculated by diffraction through crystal.

About Electromagnetic Waves
Electromagnetic waves consist of mutually perpendicular, oscillating electric and magnetic fields that also remain perpendicular to the direction of propagation. They travel through vacuum at the speed of light and include radio waves, microwaves, infrared, visible, ultraviolet, X-rays and gamma rays. Unlike mechanical waves, they do not require a material medium.
