**Part A. Index of refraction of water Instructure**

The index of refraction (n) is a measure of how much light slows down in a material. In a vacuum, all electromagnetic waves have a speed of c=3*108 m/s. In other materials, light slows down. The ratio of the speed of light in a vacuum to the speed of light in the new material is known as the index of refraction (n). The slower the wave moves in the material, the larger the index of refraction... The refractive index of the plastic is 1.46 for the red light. Calculate the angle of refraction as the ray of red light leaves the prism. This is a challenging “A grade” question requiring

**Using Pfundâ€™s Method to find the Index of Refraction**

? = angle between the light ray and a normal to the surface. In this lab, you will use Snell’s law to calculate the index of refraction for two different substances. Experimental Procedures. Place a clean sheet of paper on the cork board. You may want to pin the corners to prevent the sheet from moving. Place one of the clear blocks in the middle of the sheet with its broadest area... where n i represents the index of refraction in medium i, and ? i represents the angle the light makes with the normal in medium i. Sample Problem 1: Light travels from air into an optical fiber with an index of refraction of 1.44.

The following equations help you determine reflection and refraction angles: The law of reflection: The law of reflection shows the relationship between the incident angle and the reflected angle for a ray of light incident on a surface. how to get a business registration number with the other two cases, an incident angle of 0° refracts to an angle of 0°. For all other incident angles the refracted angle will be larger than the incident angle. At the critical angle,?' c, given by ??= ? ? ? ? ? ? ? ? c n n sin 1. (2) the refracted ray has an angle of 90°. For acrylic with an index of refraction of 1.49, the critical angle is 42.16°. At incident

- ? = angle between the light ray and a normal to the surface. In this lab, you will use Snell’s law to calculate the index of refraction for two different substances. Experimental Procedures. Place a clean sheet of paper on the cork board. You may want to pin the corners to prevent the sheet from moving. Place one of the clear blocks in the middle of the sheet with its broadest area
- Key Difference – Angle of Incidence vs Angle of Refraction The key difference between the angle of incidence and angle of refraction is the sequential order of the two angles…
- The index of refraction, n, of other transparent materials is defined through the equation: n = c/v where c is the speed of light, and v is the velocity of light in that material.
- Total Internal Reflection. When light is incident upon a medium of lesser index of refraction, the ray is bent away from the normal, so the exit angle is greater than the incident angle.
