* Light and Color: We see colors because objects absorb certain wavelengths of light and reflect others. For example, a red apple absorbs all colors except red, which it reflects.
* Water and Light: Water molecules are very small and are spaced relatively far apart. This means that the light waves can easily pass through them without being absorbed.
* Slight Blue Tint: While pure water appears colorless, it actually does absorb a tiny bit of red light. This is why deep bodies of water, like oceans, can appear slightly blue.
Key points:
* Transparency: Water is transparent, meaning light can pass through it.
* Absorption: Water molecules don't absorb significant amounts of visible light, causing it to appear colorless.
* Scattering: While water doesn't absorb much light, it does scatter some light, which is why we can see through it.
So, water is essentially a blank canvas when it comes to light absorption, which is why we see it as colorless.
