Snell's Law: measure refraction with a real protractor

Students use the Snell's Law (II) remote lab to read incident and refracted angles, calculate refractive index, compare media, and observe total internal reflection.

• Measure incident and refracted angles from the normal using the Snell's Law remote lab.
• Calculate refractive index from n = sin(i) / sin(r) when light passes from air into a medium.

Includes student questions and response prompts.

The Mystery of the Broken Straw

Solve an everyday mystery by comparing how light passes through water at 0° and 60° in the remote lab.

• Visually predict which path light will follow when it enters water.
• Qualitatively compare the beam in water at 0° and at 60°.

Includes student questions and response prompts.
