The wavelength of X-rays is of the order of:
Correct answer: C. 1 A0
- A. 10 A0
- B. 1000 A0
- C. 1 A0
- D. 100 A0
Explanation
X-rays have wavelengths in the range of 0.01 to 10 nanometers, which is approximately 1 Angstrom. This makes option C the correct answer. Options A, B, and D have wavelengths that are too large to be characteristic of X-rays.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
