About This Product
Moving an object away from the concave mirror shows the point where the image flips upside down, while the convex mirror always gives a smaller upright image, as in a vehicle side mirror. Bending a flexible sheet into an S-curve with the knobs splits a reflection into stretched and squashed parts, so students can relate the shape of a mirror to the kind of image it makes.
