Reciprocal lattice

A reciprocal lattice is a pattern of lines that can be used to study waves like light and sound. These lines form a grid-like pattern which can help scientists measure the properties of a wave, like the different wavelengths or frequencies it has. Think of the pattern like lines on a piece of graph paper. The points on the lattice represent the different wavelengths or frequencies of the wave. Scientists can measure how strong each wavelength is and this can help them understand what the wave looks like.
