Please help me with my homework! please show mehow to solve this problem.
I will give proper respect as soon as possible. PLEEEASE helpme!!! #4.20(a) When X-rays of wavelength =0.20nm are reflected offthe face of crystal, a bragg maximum is observed at a glancingangle of =17.5degree, with sufficient intensity that it isjudged to be first order. (a)What is the spacing d of theplanes that are paralel to the face in question? Answer (a) is 0.33nm (b) what are the glancing angles of all higher ordermaxima is 37.3 dgree,65.4 degree Please help me with my homework! please show mehow to solve this problem.

Explanation / Answer

wavelength = 0.2 * 10 ^ -9 m angle = 17.5 degrees from Bragg's equation 2 d sin =     for 1 st order from this spacing d = / 2 sin                               = 0.33255 * 10 ^ -9 m                                =0.33255 nm (b). 2d sin 37.3 = n from this order n = 2d sin 37.3 /                           = 2 2d sin 65.4 = n from this order n = 2d sin 65.4 /                           = 3 from this order n = 2d sin 65.4 /                           = 3
