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.

Answer: b.a categorical variable.
Explanation:
In numerical variables, such as rainfall measured in inches or the number of sales in a day, the numbers have a numerical meaning. But a categorical variable is a category such as gender and national origin. It can be represented as a number, like the Social security number, but the numbers won´t have a numerical value. If your SSN is bigger than mine, it doesn´t mean that you are greater or at a different level on a scale, because the numbers are used as categories, not as mathematically meaningful.

Answer:
a. Concept Screening
Explanation:
Because each criterion is given equal weight in the <em>concept screening</em> method, the team should be careful not to list many relatively unimportant criteria. The concept screening method is used to choose important concepts. It is important not to list relatively unimportant criteria. Each concept will be compared to a baseline concept.
