Magnification is like using a special magic power that makes things look bigger. Imagine you have a tiny bug on your hand and you want to see it closely. You can use a magnifying glass to make it look bigger. It's like when you use a toy telescope to zoom in on a far away star and see it clear and bright.
Magnification works by bending the light that comes from an object and passing it through a lens. This lens makes the object appear larger and closer than it actually is. So if you look at something through a magnifying glass, it will look bigger and more detailed than if you looked at it normally.
Scientists and doctors use magnification to see things that are too small to see with our eyes alone. For example, doctors use microscopes to look at tiny cells and bacteria to diagnose diseases. Scientists use telescopes to study stars and galaxies far away.
So, magnification is like a magic tool that makes things look bigger and clearer than they really are, helping us see the tiniest details and explore the vastness of the universe.
