# How do we define reciprocal lattice in Solid State Physics

**Does Physics confuse you? Learnt the definition and other aspects of the reciprocal lattice from this page.**In Solid State physics, we use the term reciprocal lattice for an easier approach to the X-ray diffraction by lattices. I am confused about the definition of the reciprocal lattice. I need an explanation in an easier way. Bragg defined this term as the solution to the complexities of calculations with direct lattice, how does the approach to reciprocal lattice simplify the calculations?
