Physics
1 answer:
Sloan [31]3 years ago
5 0

Answer:

The variables \eta_1 and \eta_2 depend upon the materials involved.

Explanation:

Snell's law of refraction for light traveling from one medium to another is given as:

\eta_1\times \sin \theta_1=\eta_2\times \sin \theta_2

Where,

\eta_1\rightarrow \textrm{refractive index of medium 1}\\\eta_2\rightarrow \textrm{refractive index of medium 2}\\\theta_1\rightarrow \textrm{angle of incidence in medium 1}\\\theta_2\rightarrow \textrm{angle of incidence in medium 2}

Now, the refractive index of the medium depends only upon the material of the medium. It is the property of the medium.

So, in Snell's law of refraction, the variables \eta_1 and \eta_2 depend upon the materials of the medium involved.
