To show the movement of rays from one medium to another using diagrams, you need to consider the angles of incidence and refraction, the indices of refraction of the media, and the speed of light. These variables can be used to determine the relationship between the angles of incidence and refraction using Snell's law.
The variables used to show the movement of rays from one medium to another using diagrams are the angles of incidence and refraction, the indices of refraction of each medium, and the speed of light in each medium.
When a ray of light travels from one medium to another, it undergoes a change in direction called refraction. The angle of incidence is the angle between the incident ray and the surface of the medium, while the angle of refraction is the angle between the refracted ray and the perpendicular to the surface.
The relationship between the angles of incidence and refraction can be determined using Snell's law:
n1 sin(theta1) = n2 sin(theta2)
where n1 and n2 are the indices of refraction of the two media, and theta1 and theta2 are the angles of incidence and refraction, respectively.
