Part 1 - Light Passing from a Less Dense to a Denser Medium

In this part of the lab, you are going to investigate refraction as light goes from air to water. To this, you are going to adjust the angle of incidence for the incoming light and observe the effect it has on the angle of refraction. To activate the light, click on the red button. To adjust the angle of incidence, put your cursor on the light source and drag it in the direction of the green arrows.

For each of the scenarios below, set the angle of incident to the required angle and record the angle of refraction. Use these values, along with the index of refraction for both mediums, to verify Snell's Law for each scenario.

Scenario 1:

Angle of Incidence 11	Air Index of Refraction n1n1	n1sin1n1sin1
30o	1.00	?
Angle of Refraction 22	Water Index of Refraction n2n2	n2sin2n2sin2
?	1.33	?

Scenario 2:

Angle of Incidence 11	Air Index of Refraction n1n1	n1sin1n1sin1
60o	1.00	?
Angle of Refraction 22	Water Index of Refraction n2n2	n2sin2n2sin2
?	1.33	?
