ANALYSIS
1. Describe what method can be used to locate C for a circular concave mirror.
2. Describe how to locate F for a circular concave mirror.
3. Use the measurements in Procedure #1 and #2 to calculate the ratio of r/f' How close is this ratio to 2/1??
4. (a) Through what point does an incident ray parallel to the principal axis reflect?
(b) Where does the incident ray through F reflect?
(c) Where does the incident ray through C reflect?
5. Summarize the rules for light rays that strike a circular concave mirror.
APPLICATIONS
