Optics: Curved Mirrors

PIRA Class: 6A20.10

Purpose:

To observe the reflection of a light beam (or beams) from a curved (regular) surface.

Description:

Blackboard optics with multiple rays and a curved mirror.

- The PASCO "Blackboard Optics" Chalkboard Set-Up (with magnetic mounts): Draw in normal lines, etc. directly onto the chalkboard. Make sure all is set up precisely before class, equipment's magnetic mounts are not easy to manipulate during lecture.

- The PASCO "Blackboard Optics" Lecture Counter Set-Up (directly below overhead document camera): Lay equipment on top of butcher paper (available in front office mail room) and use a marker to draw in normal lines, etc. This method is a bit more flexible classroom set-up, as it allows for equipment to be easily changed out for other demos (e.g., Reflection from a Flat Mirror) and can be more easily viewed by class.

NOTE: Do not leave equipment light sources on for very long, mounts can become very hot. Handle with care!

Blackboard Optics set, multiple ray projector, transformer
