the variables n1 and n2 in snell’s law of refraction depend upon

the angles of incidence

the materials involved

the angles of refraction

the wavelength of light

The variables and depend upon the materials involved.

Explanation:

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

Where,

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 and depend upon the materials of the medium involved.

n1 is the first medium (like air) and n2 is the second medium (like water)
