Question

For a simple cubic crystal lattice, the angle between the [201] plane and the xy plane is(a) less than 30°(b) between 30° and 45°(C) between 45º and 60°(d) greater than 60°​

Answer 1

Answer:

Take [h1,k1,l1] and [h2,k2,l2] as [2,0,1] and [0,0,1] respectively by using angle between 2 planes formula u get answer greater than 60degree
