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

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
