Answer:
Explanation:
Using the snell's law refraction to solve this problem;
According to the law, the ratio of the sine of incidence to the sine of refraction is a constant for any given pair of medium. Mathematically;
[tex]n = \frac{sin(i)}{sin(r)}[/tex]
n is the refractive index of benzene
i is the angle of incidence = 43°
r is the angle of refraction = 27°
Get the index of refraction of benzene;
[tex]n = \frac{sin 43^0}{sin 27^0} \\\\n = \frac{0.6819}{0.4539} \\\\n = 1.502[/tex]
Hence the index of refraction of benzene is 1.502
