Unit 1: Geometric Optics

Light and Shadows (Genova, 5:41)

Determining the length of a shadow on a screen, or doing similar calculations.

Can They See Each Other? (Genova, 2:56)

When given the placement of two people and a flat mirror, determine if they can see each other.

Where Should the Mirror Go? (Genova, 3:20)

Given two people's locations in a room, where would you place a flat mirror so they can see each other?

Refraction (Genova, 5:58)

How to determine if lights speeds up or slows down when it enters a new medium, and which direction will it bend.

Investigating an Unknown Medium (Genova, 3:55)

Using the Phet simulator to estimate the index of refraction of an unknown medium.
