Question

1. The first order diffraction peak of a crystalline solid occurs at a scattering angle of 30° when the diffraction pattern is recorded using an x-ray beam of wavelength 0.15nm. If the error in measurements of the wavelength and the angle are 0.01nm and lº respectively, then the error in calculating the inter- planar spacing will approximately be: [NET Dec. 2015] (a) 1.1x10-2mm (b) 1.3x10 41 22711 nim (c) 2.5x10-?nm I. (d) 2.0x10-'nm ​
