Aray diagram is shownwhich statement best describes the diagram? the diagram shows refraction, and medium 1 is denser than medium 2. the diagram shows refraction, and medium 1 is less dense than medium 2. the diagram shows reflection, and medium 1 is less dense than medium 2. the diagram shows reflection, and medium 1 is denser than medium 2.

The diagram shows refraction, and medium 1 is less dense than medium 2.

Explanation:

- Reflection occurs when a light ray hits a surface and bounces back into the same medium

- Refraction occurs when a light ray crosses the interface between two different mediums, changing direction

From the diagram, we clearly see that this is a case of refraction, since the light ray crosses the boundary between two mediums.

The direction of a light ray in refraction is given by Snell's Law:

(1)

where

n1 and n2 are the index of refraction of the two mediums: a higher index of refraction means a higher density for the medium

are the angles of the light ray in medium 1 and medium 2, measured with respect to the normal to the interface

We can rewrite eq. (1) as

From the diagram, we see that

so

and so

which means

so, medium 2 is denser than medium 1, and the correct answer is

The diagram shows refraction, and medium 1 is less dense than medium 2.

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

elly's long hair:

a. if the salon only takes cash, then this isn't the problem. it doesn't matter how much she has in her checking account.   she can't get a haircut until she has the cash.

b. if she has overdraft protection, then there's no problem.   she can go ahead and write a check that her account can't cover, then sometime later, pay the bank some outrageous usury for loaning her a few bucks for a few days, but with beautiful hair.

c. if elly has some principles, and doesn't want to write a bad check, then now she has a problem.   her desire for the new hairstyle is in conflict with her honesty and integrity.

d.   if the bank will not process a check she writes, then even if she had a million $$ in her account, she couldn't use any of it.   the amount she has in her account is not the problem.   and if i may suggest, she might as well close her checking account, and put the money where it'll work for her.   it's not doing her a bit of good in a checking account, since she can't write any checks.

justin can't pay the full balance:

a. he can't even handle the credit limit he has now.   under no circumstances should he ask for a higher limit.

b.   he can ask for the grace period to be extended.   but that's no solution, the bank will almost certainly refuse anyway, and there are much better options.   he knew the rules of his credit card when he started using it.

c.   he definitely should pay the interest on the balance, plus as much of the balance as he can cover at the same time.

d.   he definitely should pay the minimum otherwise they could shut down his card.   he should also pay as much more as he possibly can.   he should also remember the awkward situation he's in, stop buying stuff on credit that he can't afford, and avoid adding any more debt.

i'd say that justin's best best option isn't on this list of choices.   what he has to do:   pay as much as he can at least the minimum payment plus as much more as he can and then avoid adding more debt.
