Enlarging an image
HERE’S HOW
. Place the lenses mm apart, facing
towards a window as shown. Use a ruler or
two rods to align the lenses perfectly.
. Focus on an object outside the window.
Move the fog lens slowly back and forth,
and an image of the object will appear on
the fog filter.
WHAT’S HAPPENING
An image of the object you are viewing appears on the fog lens. The
image appears inverted, or upside down. Changing the distance
between the lenses will make the image more or less clear, or
focused. Note the optimal distance between the lenses, and the size
and brightness of the image. Now compare this to Experiment .
