A nearsighted student with a far point of 6.30 m wears contacts that allow him to see distant objects clearly. When the student views a 2.20 m high tree that is 18.6 m away though his contacts, determine the following.
(a) image distance for the tree
m
(b) image size (absolute value), that is the height of the tree
Once can set up a two-dimensional scattering theory that could be applied to puck projectiles sliding on an ice rink and colliding with various target obstacles.
