Question

Why can you see through water? (From a real 4 y.o.)

In: Physics

Answer 1

You can see thanks to light (from the Sun or a lamp or whatever).

Water, like air and glass, is transparent. This means that when light reaches water, most light passes through the water without being “absorbed” (blocked) or “scattered” (bounced back).

Therefore you can see through water, or air, or glass.

Objects are transparent or not depending on how they are made inside, in particular how extremely tiny particles are made and positioned.
