A cross section of the human brain as drawn in Gray's Anatomy. MRI is one of the most exciting and complex applications of a physical concept, resonance , that underlies many elements of our lives.

It is important, therefore, to first be familiar with wave phenomena and properties. You can directly observe various wave types, properties, and phenomena with a flip of a wrist.
