It takes nd/ (lambda*f) time or a short pulse of light to travel from one end of the glass to the other.
If we talk about free space, that is, vacuum, light travels at a speed of 3x10^8 m/s, yet inside a glass light travels at a speed of v= c/n, where v is the velocity of the light and n is the refractive index. Now,
v=d/t,
so t= d/v
t= d/ (c/n)= n*d/c
c= lambda*f
t= nd/(lambda*f)
here, d is the thickness of the block, t is the time required and c refers to speed of light.

Explanation:
He strengthened royal courts by having the jury formally accuse a person of having committed a serious crime. He introduced the courts that were governed by the King and that would put subjects on trial, which weakened the feudal lords who had that power earlier.
There are several reasons why couples get a divorce, and here are the most usual ones:
- if they have been divorced before, or if their parents were divorced when they were still kids
- if they married at a young age (anything before 20s)
- if they had children very quickly after getting married
These are some of the reasons why couples might get a divorce and why there are so many of them.
