HOPE THAT HELPED A LITTLE
It would be D, because energy can’t be created OR destroyed. In answer A, it mentions converted to other forms, but it also mentions that it can be created and/or destroyed. Therefore, the answer is D.
Answer:
The ratio of the refractive indices of the liquids is 1.22
Solution:
Critical angle for A and B interface,
Critical angle for A and B interface,
Now,
From the relation in between the critical angle and refractive index:
(1)
where
n = rafractive index
= critical angle
Thus
For AB interface:
For AC interface:
Thus the ratio of the refractive indices of these liquids can be given as:
