   A ray diagram is a representation of the possible paths light can take to get from one place to another. This is often from a source or object to an observer or screen. There are a few important things to note: Light travels in straight lines within a uniform medium (this means that light can change direction upon entering a different medium).

   The incident ray refracted ray, and the normal to the interface of two media at the point of incidence all lie on the same plane. The ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant. This is also known as Snell’s law of refraction.

   Apr 21, 2020 · The incident ray, the refracted ray, and the normal lie in the same plane. Snell’s law: It is an equation connecting the angles of incidence and refraction with the refractive indices of the two mediums. Snell’s law is used to find the angle of refraction or the refractive index of a material (e.g., a glass slab).

   Sep 27, 2020 · (a) A ray of light moves closer to the perpendicular when entering a medium with a higher index of refraction. (b) A ray of light moves away from the perpendicular when entering a medium with a lower index of refraction. The amount that a light ray changes its direction depends both on the incident angle and the amount that the speed changes.

   How do you draw a ray diagram?

   • In a ray diagram, you draw each ray as: with an arrowhead pointing in the direction that the light travels. Remember to use a ruler and a sharp pencil. Investigating the law of reflection On a sheet of white paper draw a pencil line – label this AB. Using a protractor, draw a normal at C, roughly the middle of AB. Draw a line at 20 o to the normal.

   Is a ray diagram the same if the object is located?

   • It should be noted that the process of constructing a ray diagram is the same regardless of where the object is located. While the result of the ray diagram (image location, size, orientation, and type) is different, the same three rays are always drawn.

   What is a refracted ray?

   • Incident Ray: The ray of light that is incident on the interface. Refracted Ray: The ray of light that is refracted at the interface. Normal: An imaginary line perpendicular to the interface. Angle of Incidence: The angle that the incident ray makes with the normal. Angle of Refraction: The angle that the refracted ray makes with the normal.

   How does refraction affect the direction of a light ray?

   • The change in direction of the light ray depends on the relative values of the indices of refraction of the two media involved. In the situations shown, medium 2 has a greater index of refraction than medium 1.

   How does a light ray change its direction?

   • Based on the refractive index of the medium, the light ray changes its direction, or it bends at the junction separating the two media. If the light ray travels from one medium to another of a higher refractive index, it bends towards the normal, else it bends away from the normal.
