PIRA Class: 6A10.10
Purpose:
To observe the reflection of a light ray(s) from a flat (regular) surface.
Description:
Blackboard optics with single or multiple rays and a plane 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 Curved 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!
