Question

A ray of light approaches a jar of honey at an angle of 30.0. If the angle of refraction is 19.5, what is the refractive index of honey?

Answer 1

Answer:

n = 1.49

Explanation:

Given that,

Angle of incidence = 30 degrees

Angle of refraction = 19.5 degrees

We need to find the refractive index of the honey. Using Snell's law, we can find it as follows :

$n=\dfrac{\text{sin i}}{\text{sin r}}\\\\=\dfrac{\text{sin 30}}{\text{sin 19.5}}\\\\n=1.49$

So, the refractive index of honey is 1.49.
