What is Light travels through more air?

Light travels through more air when it goes on a longer journey, just like how you walk farther if you take a bigger trip around the block.

Imagine light is like your friend who loves to run. When your friend runs from one end of the park to the other, they go through more grass than when they just sprint from your house to the corner store. Light works similarly, when it goes through more air, it has a longer path to travel.

Think about a sunny day. The sunlight coming from the sun has to travel all the way through space and then into our atmosphere, which is made mostly of air. If you're standing outside on that sunny day, the light has already traveled through lots of air before it reaches you.

Now imagine you’re inside a big, empty room with nothing but air around you. Light coming from a lamp in one corner travels through the whole room, and that means it goes through more air than if it just went across your bedroom.

So whether light is traveling from the sun to Earth or from a lamp to your face, it always takes a longer path when it goes through more air, like you taking a bigger trip around the block.
