When a spherical body goes by a viscous fluid, it feels a viscous force. The value of the viscous force increases with the enhance in speed of the object falling under the function of its weight. As a result, the viscous force soon becomes the driving force and the object starts rolling with a constant speed, called as its terminal velocity. Let us now produce a relation for the terminal velocity, as an application of stokes' principle.
What do you mean by lateral shift? Derive a mathematical expression for lateral shift produced by a parallel sided glass slab for oblique incidence.
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.
