Concave and Convex Mirrors

The objective of this experiment is to explore the images formed by convex and concave mirrors.  

CONVEX MIRROR:

For a convex mirror the object appears larger than the image and is upright.  If one moves the object closer to the convex mirror, then the image becomes a bit larger but still smaller relative to the size of the object.  The image also gets a little bit closer.  Moreover if  object moves farther away from the convex mirror, then the image gets smaller, the image is farther away, and remains upright.

The convex diagram is an emblem of the observation made during the activity.

For Convex Diagram (left):
height of object Ho= .031 meters
height of image Hi = .007 meters
Distance of object Do = .062 meters
Distance of image Di = -.019 meters

Magnification M = Hi/Ho = .226

CONCAVE MIRROR:

For the concave mirror, the image is inverted and much larger than the object.  When the object is retreated to a large radius, the object remains inverted and becomes larger.  However if the object is moved close enough to the concave mirror, the image becomes up right and smaller.

This concave diagram is a representation of the observations made during the activity.

For Concave Mirror (left):
Ho = .031m
Hi = -.007 m
Do = .113 m
Di = .023 m

M = Hi/ Ho = -.258
