Above the aisle of a corner store hangs a big round mirror. Jorun glances up and sees the whole aisle at once: shelves, carts, shoppers, all tiny and right side up.
The convex mirror has one profile for every object distance. This lesson states it, and says why stores hang exactly that mirror.
Move an object anywhere in front of a convex mirror: near, far, anywhere.
The image stays behind the mirror, right side up, and smaller than the object.
Unlike the concave mirror, the convex mirror has no second case. Every object distance gives the same three words.
Reduced is the useful part. Because every image is small, images of a whole aisle fit into one small mirror at once: a wide field of view.
That is why the store hangs a convex mirror: one glance at it covers the whole aisle.
Three mirror kinds, and every profile now stated. The table collects them.
A delivery van's rear door mirror is convex. A cyclist rides behind the van. Which profile fits the cyclist's image?
A convex mirror forms the same kind of image at every object distance.
The profile is virtual, upright, reduced.
The cyclist's image is virtual, upright, and reduced.
A school bus's blind-spot mirror is convex. Why does the small mirror show the whole side of the bus at once?
A convex mirror's images are always reduced.
Each thing beside the bus appears small, so images of many things fit into the one small mirror at the same time.
The reduced images of the whole side of the bus fit into the small mirror together: a wide field of view.
A trash can stands 3 m from a convex security mirror. Which profile fits its image?
One small convex mirror at a warehouse door shows the whole loading area at once. Why does so much fit into the mirror?
Katla says: 'However far away the object stands, a convex mirror's image is virtual, upright, and reduced.' Is Katla correct?
A shopping cart rolls toward a convex mirror hung over a store door, from 8 m away to 2 m away. Which option describes its image during the whole roll?
A driveway mirror at a blind corner is convex. Why does it show the whole street in one small mirror?
Lennart lists the three mirror kinds he has met: plane, concave, and convex. Which of them can form an image that a screen catches?
