curved mirror/lenses equation Flashcards
memorize
state the curved mirror and lens equation
1/F = 1/di + 1/do
state the magnification equation
m = -di/do
m = hi/ho
negative F means
mirror is convex and lens is concave (DIVERGING)
positive F means
mirror is concave and lens is convex (CONVERGING)
negative di means
image is real and inverted
positive di means
image is virtual and upright
positive hi means
image is upright
negative hi means
image is inverted
for lenses, negative m means
image is real and inverted
for mirrors, negative m means
image is virtual and upright
