A rectangular glass prism of thickness d and absolute refractive index n is placed on a point object which is viewed vertically downward from above the prism. Which of the following expressions correctly defines the apparent upward displacement of the object?
A
\(\frac{d}{n}\)
B
dn
C
\(\frac{d}{n - 2}\)
D
\(\frac{d(n - 1)}{n}\)
Verified Correct Answer: A.
Physical Principles & Numerical Solution
n = \(\frac{R.d}{A.d}\)
R.d = \(\frac{R.d}{n} = \frac{d}{n}\)
