[hcchong]

The distance between the primary planes of a NaCl crystal is 2.82 Å. It was found that the first order Bragg reflection of a monochromatic x-ray beam occurs at sinus= 10 degree. (i) Determine the wavelength of the x-ray. (ii) Determine the angle, sinus for a second order reflection.

You have to post your attempt at the question. At least state the things that you know and what you find troubling. Even just post Bragg's law.
