A coin is resting on the bottom of an empty container. The container is then filled to the brim three times, each time with a different liquid. An observer (in air) is directly above the coin and looks down at it. With liquid A in the container, the apparent depth of the coin is 7 cm, with liquid B it is 6 cm, and with liquid C it is 5 cm. Rank the indices of refraction of the liquids in descending order (largest first). a. nA, nB ,nC
b. nA, nC ,nB
c. nC, nA ,nB
d. nC, nB ,nA

Explanation:

index of refraction = real depth / apparent depth .

apparent depth is in the denominator so as it decreases , index of refraction increases .

Apparent depth is least for C , so index of refraction of C will be greatest .

So required order largest to least is C , B , A.

d ) is the correct option.

float.

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
