Even though Water is Colorless, How Does It Make the Place Where It Spills Dark?

Think about places when it rains. It will be a much darker color compared to its dry state, right? For example The area that is gray when dry turns black when wet. disguises itself. The same goes for most things that get wet.

Well, let me tell you that there is actually no such darkening situation, We are experiencing some kind of optical illusion. What do you say if we tell you? Let’s explain right away.

Wet fabric or ground is not darker compared to dry area, but it appears darker to our eyes.

This is actually related to how colors are reflected in our eyes and how we perceive them. Light from any light source (sun, lamp, etc.), hits an object and some of this light is absorbed while the other part is reflected. The wavelength of the light coming from the object to our eyes determines what color we perceive the object is.

For example, a yellow t-shirt, It absorbs light of all wavelengths except those that create the yellow color and reflects the rest to the surroundings. The same applies to wet places. How exactly?

In a way, the water plays with the settings of the reflection.

When water spills on us or somewhere, this area is covered by a layer of water. So when the light hits a wet place; this layer of water The yellow t-shirt causes the yellow wavelengths of light to be reflected less into our eyes and the yellow light to be refracted more. causes.

Since water has no color, it absorbs the color of the area it covers and changes the angle at which light hits the shirt. To summarize, water helps the surface absorb more light hitting it and change in reflected color is occurring.

In short, the bad news is that unless our perception of light changes (which is probably never), when our armpits sweat to give ourselves away as an image we will continue…
