Answer:
The angle of separation is   
 
Explanation:
From the question we are told that 
     The angle of incidence is  
      The refractive index of violet light  in diamond  is  
        The refractive index of red light in diamond is 
       The wavelength of violet light is   
 
          The wavelength of red  light is   
 
 
Snell's  Law can be represented mathematically as 
          
Where  is the angle of refraction
 is the angle of refraction 
=>       
Now considering violet light 
                
substituting values
                 
                  
                  
                  
Now considering red light 
                
substituting values
                 
                  
                  
                  
The angle of separation between the red light and the violet light is mathematically evaluated as 
                   
substituting values

Answer:
  r =  1.45 Å
Explanation:
given,
λ = 1.436 Å 
θ = 20.62°
 d = a
 n = 2 
metal gold crystallizes in a face centered cubic unit cell
Radius of the gold atom = ?
using Bragg's Law
  n λ = 2 d sin θ
  2 x 1.436 Å = 2 a sin 20.62°
  a = 4.077 Å
We know relation of radius for face centered cubic unit cell
  
  
   r =  1.45 Å
 the radius of a(n) gold atom. is equal to 1.45 Å
