Introduction
💦
There are 2 reasons that make us see the ocean blue. 🌊
First, it depends on how humans see light waves from the sun. 🔆
Second, distance from the water source is also a factor. 🚿

Light Spectrum
💥
The human eye can only see a narrow
spectrum of sunlight called the visible spectrum. 👁👁
When the sun shines on the ocean, all colors of light enter the water. However, only the green and blue spectrum of light get reflected by the human eye.🟢🔵
Blue Ocean & Clear Bathtub Water
The color of water can seem very different depending on distance, too.
A bathtub or glass full of water always looks clear, letting you see your reflection.
This is because it is being viewed over a short distance.
In fact, if the volume of water was sufficiently large, would it appear blue.
The color of water is nor always the same, depending on the water source
the reason of different color of water is that deep water only transmits a small amount of blue light. The deeper the water, the darker the ocean seems
Oxygen also affects the darkness of the color. Sunlight is often scattered by oxygen in the water, making it harder to reflect the blue light
