Doppler Effect
Describing the classical Doppler Effect for sound waves. The Doppler Effect is a means through that wave properties (specifically frequencies) are influenced through the movement of a source or listener. If you've ever been waiting at a railroad crossing and listened to the train whistle, you've in all probability noticed that the pitch of the whistle changes as it moves associatively to your position. Same, the pitch of a siren change as it approaches and then passes you on the road.
Advantages of fibre optics: Fibre-optic communications systems have a large bandwidth, e.g. 1 GHz. The bandwidth is the maximum rate at which information can be transmitted.
Determine the surface integral for the vector function over the surface S. where S is the surface of the unit cube bounded by x=0, x=1, y=0, y=1, z=0, z=1.
Using the Maxwell's equation explain that electromagnetic waves transverse in nature.
