mλ=2dsin(θ) this relation is called:
Correct answer: B. Bragg's Law
- A. Coulomb's Law
- B. Bragg's Law
- C. Faraday's Law
- D. Ohm's Law
- E. Gravitational Law
Explanation
The equation of Bragg's Law is mλ=2dsin(θ), where m is the order of the diffraction, λ represents the wavelength of the incident wave, d is the interplanar spacing, and θ is the angle of incidence.

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.
