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:
moral reasoning
Explanation:
Moral reasoning is a study in philosophy known as moral philosophy which also overlaps in studies in psychology known as moral development. Moral reasoning is critical analysis to events that may have to deal with moral dilemmas to determine what is morally wrong or right in such situations. Logic and moral theories are typically applied to these analysis(such as utilitarianism) to break down and clarify moral events.
Answer:
They can influence the mass media
Explanation:
Public Agenda is the issue that most people in the country will be focused on. This could include both economic, socio-cultural, or foreign relations.
Every times the national government propose a certain bill or regulation to handle a certain issue, the media will pick up on it.
When the news is presented to the public, a nationwide conversation will occurs among the citizens to discuss that topic. Some might support it, while some might oppose to it.
This will eventually form a popular public opinion regarding how we as a nation could address the issue, and a public agenda is formed.
