About This Product
Moving an object away from the concave mirror shows the point at which its image turns upside down, while the convex mirror always gives a small upright image like a vehicle side mirror. Flexing a distortion sheet into an S-curve splits a reflection into stretched and squashed parts, so students can see how changing the curve changes the image.
