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.

Charise, who has just studied personality psychology in school, corrects Noreen by saying
a. "You're probably right, Noreen. Freud was really into subconscious motives."
Explanation:
In Sigmund Freud's theory subconscious is present as the plane of consciousness that is not readily accessible but operates from the back of our minds and makes sense of our actions that do not seem done consciously.
One of the telltale signs of this is actions like this which have little basis in actual reasons but people do anyway because they enjoy them or their subconscious is telling them to do them. One of these is also the famous Freudian slip
