Exploring reflections
Report sheet
Name
Objective: To 1) discriminate real images from virtual images, 2) learn more about geometrical optics with flat mirrors, and 3) observe real images from a concave reflecting surface.
Data:
Distance between the Post-It notes on the mirror (that is, the height ot Flat Albert’s
image) in cm:
Flat Albert’s actual height, in cm
How does Albert’s apparent height in the mirror compare with his actual height?
What happened to the fit between Albert’s image and the marks on the mirror as you moved back and forth from the mirror?
11.1
Briefly describe your image in the back of a spoon:
Is that image virtual or real? How do you know?
Briefly describe your image in the bowl or front of a spoon:
Is that image virtual or real? How do you know?

Why do catadioptric or Cassegranian telescopes use both concave and convex mirrors?
