"An image is formed by a lens when light from every point on the object intersects at a location in space." That's nice theory, but it's a little difficult to get a mental grip on. But now that has changed with our Converging Lens Image Formation simulation. Tap the link and watch as our Interactive constructs the image of every point on an object using a rapidly-draw ray diagram. The process and the result will fascinate you. Tap the link and secure your grip on image formation.
