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.

Those who attribute their poor performance to a lack of ability or to situations beyond their control<u> "demonstrate pessimism".</u>
Nowadays everyone is by all accounts discussing confidence and constructive reasoning yet for a few people who are pessimistic such an exhortation sounds strange.
Actually we can't accuse a pessimistic individual for not tolerating such exhortation about positive thinking in light of the fact that a guidance can just work when it coordinates the individual's conviction framework.
Pessimism can surely aggravate your life, increment your awful temperaments and even outcome in depression. In my book, a definitive manual for getting over depression we clarified how sadness can be simply a condition of loss of expectation a man comes to in the wake of getting to be skeptical.
