From the diagram above, the sine of the angle of refraction in glass is
Attached Figure / Diagram
A
0.4
B
0.3
C
0.2
D
0.1
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
\(_ag_g\) = \(\frac{\text{sini}}{\text{sinr}}\)
sinr = \(\frac{\text{sini}}{_ag_g}\)
sinr = \(\frac{0.5}{1.5}\)
sinr = 0.3
