1.50
1.67
2.50
Correct answer is D
n = \(\frac{\text{real depth}}{\text {apparent depth}}\)
\(\frac{10}{10^{-4}}\) = 1.6
10.5o
19.5o
21.1o
38.9o
40.5o
Correct answer is A
n = \(\frac{sin i}{sin r}\)
sin r = \(\frac{30^o}{n}\)
sin r = \(\frac{0.5}{1.5}\)
sin r = 0.3333
r = 19.5o; Deviation 30 - 19.5 = 10.5o
