Lab 10: Angle of refraction of the chosen liquid
Purpose: Applying knowledge learned throughout the chapter to see the process of refraction,
as well as set up an experiment to test Snell’s Law.
Materials:
-Refraction cell or a transparent container with flat, parallel sides
-Laser pointer
-Paper
-Pen
-Water
-Protractor
-Straight edge or ruler
Procedures:
1. Set up workspace in a dimly lit room to clearly observe the laser beam's path.
2. Fill the refraction cell with water
3. Place the refraction cell on a flat surface.
4. Set up the laser pointer so that it emits a beam of light perpendicular to the surface of the
water in the refraction cell. You may need a stand or support to hold the laser pointer steady.
5. Place a piece of paper behind the refraction cell to create a surface for the laser beam to
strike and make its path visible.
6. Turn on the laser pointer and direct the beam to pass through the water in the refraction
cell. Ensure that the beam enters the water at a right angle to minimize distortions.
7. On the paper behind the refraction cell, mark the entry point and exit point of the laser beam
as accurately as possible. You may need an assistant to help with this step.
8. Measure the angle of incidence (the angle between the incident beam and the normal line)
using the protractor. Ensure that the normal line is perpendicular to the surface of the water at
the point of entry.
9. Measure the angle of refraction (the angle between the refracted beam and the normal line)
using the protractor. Ensure that the normal line is perpendicular to the surface of the water at
the point of exit.
