✦ Synopsis

A theoretical study is carried out to investigate the difference in the properties of an electromagnetic wave reflected from a fixed object and a moving object. Solutions of a wave equation in rectangular coordinates are used with different boundary conditions for the determination of the reflected wave characteristics.

The variation in the values of angle of incidence and reflection with time, as an object moves, are shown to be related to Doppler frequency as well as the relative velocity. Expressions for an electromagnetic wave refected from both the fixed and moving object are given. A relationship between relative velocity with respect to the source of incident wave and the reflected wave frequency and amplitude is described.
