Set the top medium to AIR. Set the second medium to CUSTOM. Move the slider for the index of refraction to 1.41.
2) Use Snell’s Law to find the following (show your work): If θi = 45°, what is the value of θr?

Explanation:

Refraction is a phenomenon that occurs when light passes through the interface between two mediums.

When this occurs, the ray of light changes speed and also changes direction, according to Snell's Law:

is the index of refraction of the 1st medium

is the index of refraction of the 2nd medium

is the angle of incidence (the angle between the incident ray and the normal to the boundary)

is the angle of refraction (the angle between the refracted ray and the normal to the boundary)

For this problem we have:

is the index of refraction of the 1st medium (air)

is the  index of refraction of the 2nd medium

is the angle of incidence

Solving for the angle of refraction, we find:

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
