I really don't understand this my teacher didn't explain it at all! Please Help! Thanks so much!
1.You will now use your data from Table 1 to calculate the index of refraction of the glass. Because the medium you are leaving is air, you may leave the variable n1 out of your equation. The equation now becomes
n1 sin 1 = n2 sin 2
n1 = 1.00
Therefore you may use
n2 = sin 1/ sin 2
In this equation the following variables are used:
n2 = the index of refraction for the medium that contains the angle of refraction
sin 1 = the sine of the angle of incidence
sin 2 = the sine of the angle of refraction
A.What is the value of the index of refraction for trial 1? Show your work and record your answer in Table 1.
B.What is the value of the index of refraction for trial 2? Show your work and record your answer in Table 1.
2.Now that you have completed the table, copy Table 1 into the assignment.
3.Look at your calculated values for the index of refraction. Compare the index of refraction for trials 1 and 2.
4.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.
A.Did the light bend toward or away from the normal as it passed from air into the top of the glass plate?
B.Did the light bend toward or away from the normal as it passed from the bottom of the glass plate into the air?
