Diffraction can be treated as a highly theoretical subject, although the under lying process can be visualised quite readily. It is usually interpreted in terms of the wave nature of electromagnetic radiation, although there is an argument that quantum uncertainty provides a better physical description. Whatever the case, this chapter uses the concept of radiowaves to describe the cause and effects of diffraction.
