In the x -ray reflection ( n =1) , the distance between two parallel planes of NaCl is 280 pm and diffraction angle is 5.2^ . What is the wavelength of it's light radiation (Sin .5.2^ =0.09 )
Options
- A0.504 ~A ^
- B5.04 ~A ^
- C50.4 ~A ^
- D504 ~A ^
Correct answer
A. 0.504 ~A ^
Step-by-step solution
From Bragg's equation :- aligned n & =2 ~d & = 2 ~d n = 2 (280 10⁻¹² )(0.09) 1 & =5.04 10⁻¹¹ ~m & =0.504 10⁻¹⁰ ~m & =0.504 Å aligned
