Question

find the equation of royal dispersion of light,??????​

Answer 1

First, let’s investigate some of the properties of light. The speed at which a beam of light travels depends on the medium (for example, glass, air or water) that it’s travelling through, and for a given medium we can compute the refractive index

n=c/v

where  

c

is the speed of light in a vacuum, and  

v

is the speed of light through the medium. For air  

n

is close to 1, while for glass it is about 1.5—so light travels slower through glass than through air. Light (nearly) always takes the fastest path from A to B (that is, of course, how it gets everywhere so quickly) and the difference in speed between air and glass means that the shortest path in terms of distance may not be the fastest one.
