Assume that the distance from your eyes to your toes is 165 cm. You are standing 200cm in front of an infinitely large flat, upright mirror.
a. Draw a ray diagram for the rays from the top of your head and from your toes to your eyes.
b. Draw a virtual image of your body. How tall is the image? How far is it from the mirror?
c. Show on the diagram what part of the mirror can be covered so you still see the image.
d. Use a ray diagram to determine how far it is from your eyes to the image of your toes.
The owner of a van installs a rear-window lens that has a focal length of -0.330 m. When the owner looks out during the lens at an object located directly behind the van, the object appears to be0.250 m from the back of the van, and appears to be 0.3..
