Which one of the following cannot measure wavelength of X-rays in anyway:
Correct answer: B. Diffraction grating
- A. Bragg's law
- B. Diffraction grating
- C. Compton effect
- D. Photo electric effect
Explanation
Diffraction gratings are not suitable for measuring the wavelength of X-rays due to their much shorter wavelengths compared to visible light. While Bragg's law, the Compton effect, and the photoelectric effect can all be used to measure X-ray wavelengths, diffraction gratings are specifically designed for visible light and are not applicable to 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.
