a. Identify and describe the wave behavior as the light rays pass through the glass lens.

b. Identify and describe the wave behavior as the light rays strike the mirror.

c. Copy the dotted box from the camera diagram into your Student Answer Booklet. Draw what must happen inside the box for light ray 2 to strike the viewfinder. Be sure to include
the following:
• either a lens or a mirror that is labeled
• the path of light ray 2
• a line normal to the surface where light ray 2 strikes
