In this neat experiment, we will know how an eye lens works.
Things Required:
Magnifying lens
Sheet of typing paper
Ruler
Directions:
Darken a room. Hold the magnifying lens about 5 feet (1½ m) from an open window. Position the paper on the opposite side of the lens from the window.
Slowly, move the paper back and forth from the lens until a clear image of the window and objects outside appear.
This Is What Happens:
A small, coloured, inverted image forms on the paper.
Science Behind It:
Just like the lens in a human eye, the light changes direction as it passes through. The light hits the paper as light hits the retina when it passes through the lens of an eye and forms an inverted image.
