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?

The refractive index of honey will be "1.49".

Given:

Angle of incidence,

Angle of refraction,

As we know, the formula:

→

By substituting the values, we get

→                                    

→                                  

Thus the above answer is right.

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 :

So, the refractive index of honey is 1.49.
