1170 - What is the relationship between refraction of light and the ability of a magnifying glass to focus and project an image?

When light passes from one substance (like air) to another (like glass), it bends - this is called refraction.

In a magnifying glass, the curved lens makes the light bend to one point, focusing it. This is how a magnifying glass can make things look bigger.

The focused light is then projected as an image that you can see. So, the refraction of light in the magnifying glass helps create and project the enlarged image you see when using it.
