Question
***You don't even have to do the experiment***Help me with the table***
Purpose: To calculate the index of refraction of glass plates by measuring the angle of incidence and the angle of refraction
Introduction: We have learned that light rays are "bent" as they pass at an angle from one medium to another. We also learned that different transparent materials have differing optical densities. By measuring the angle of incidence and the angle of refraction for light rays entering the glass plates (or glass baking dishes filled with water), the index of refraction and speed of light in the glass can be calculated. My former students always seemed to enjoy this lab activity. The usual comment was, "It works!"
Materials: white paper, protractor, glass baking dish, metric ruler, and scientific calculator
You may use the following virtual site if you do not have a glass baking dish at home. Select monochromatic light of wavelength 400 nm and water for the medium.
Refraction of Monochromatic Light
Procedure:
Data:
Table 1
Questions:
What is the value of the index of refraction for trial 1? Show your work and record your answer in Table 1.
What is the value of the index of refraction for trial 2? Show your work and record your answer in Table 1.
Now that you have completed the table, copy Table 1 into the assignment.
Look at your calculated values for the index of refraction. Compare the index of refraction for trials 1 and 2.
Look at the diagram you made for trial 1. It should be similar to the one shown below. The line you drew connecting the incident ray and the ruler line (shown in red) represents the path of light in the glass.
Did the light bend toward or away from the normal as it passed from air into the top of the glass plate?

Explanation / Answer
Given Angle of incidence, i = 30^0 Refractive index of incident medium , n1 = 1.0 Refractive index of refractive medium(glass) , n2 = 1.52 From Snell's law n1sin i = n2 sin r sin r = (1.0/1.52) sin30 r = 19.20^0 Thus the angle of refraction is 19.2^0 ----------------------------------------------------------------------- Angle of incidence, i = 40^0 Refractive index of incident medium , n1 = 1.0 Refractive index of refractive medium(glass) , n2 = 1.52 From Snell's law n1sin i = n2 sin r sin r = (1.0/1.52) sin40 r = 25^0 Thus the angle of refraction is 25^0 Refractive index of refractive medium(glass) , n2 = 1.52 From Snell's law n1sin i = n2 sin r sin r = (1.0/1.52) sin30 r = 19.20^0 Thus the angle of refraction is 19.2^0 ----------------------------------------------------------------------- Angle of incidence, i = 40^0 Refractive index of incident medium , n1 = 1.0 Refractive index of refractive medium(glass) , n2 = 1.52 From Snell's law n1sin i = n2 sin r sin r = (1.0/1.52) sin40 r = 25^0 Thus the angle of refraction is 25^0 Angle of incidence, i = 40^0 Refractive index of incident medium , n1 = 1.0 Refractive index of refractive medium(glass) , n2 = 1.52 From Snell's law n1sin i = n2 sin r sin r = (1.0/1.52) sin40 r = 25^0 Thus the angle of refraction is 25^0 Refractive index of refractive medium(glass) , n2 = 1.52 From Snell's law n1sin i = n2 sin r sin r = (1.0/1.52) sin40 r = 25^0 Thus the angle of refraction is 25^0Related Questions
