Which of these object are concave, plane or convex?
full-length bedroom mirror, make up mirror, car rear-view mirror, dental mirror, store security mirror, jeweller’s mirror car side-view mirror, mirror in flashlight, shaving mirror, surface of lake. Tell me why
Under ideal conditions–ignoring hot days, cold air, and defects in manufacture….
full-length bedroom mirror: plane, to accurately reflect the image.
make up mirror: concave, to act as a magnifier.
car rear-view mirror: plane, for accurate viewing
dental mirror: plane, for accurate viewing.
store security mirror: convex, for wide-angle view
jeweller’s mirror: concave, to act as a magnifier.
car side-view mirror: convex, for wide-angle view
mirror in flashlight: concave, to focus the light; it’s usually a parabolic reflector.
shaving mirror: concave, to act as a magnifier.
surface of lake: very slightly convex! The surface of the water is equidistant from the center of the earth, making it curve–see the surface of the ocean and the horizon for an example. But the curve is so slight, most people would regard it as a plane surface.
