We can see this if we put a teaspoom into a glass of water. The image of the spoon appears to bend or be broken.
This is because air and water are materials with different densities.
Refracted light makes objects look different. ]]> 2020-06-04 14:21:00 UTC https://padlet.com/luispinedaacor/g7epbpnjfavfxdey/wish/611110997 luispinedaacor https://padlet.com/luispinedaacor/g7epbpnjfavfxdey/wish/611115766 A lens is acurved piece of glass or transparent plastic that refracts light and can make objects look bigger and smaller.

Convex lenses (positive lenses) bend the light inwards.
Magnifying glasses and microscopes use convex lenses.
Concave lenses (negative lenses) spread the light outwards.
Projectors use concave lenses.]]> 2020-06-04 15:01:27 UTC https://padlet.com/luispinedaacor/g7epbpnjfavfxdey/wish/611206384 luispinedaacor https://padlet.com/luispinedaacor/g7epbpnjfavfxdey/wish/611211503 2020-06-04 15:03:42 UTC https://padlet.com/luispinedaacor/g7epbpnjfavfxdey/wish/611211503
