MidLand, Jakarta – Awan it is one of the objects in the sky usually visible during the day. Quoted from Weatherclouds are made up of small water droplets called cloud drops.
These drops are not immediately visible to the naked eye. But if you look under the microscope, you will see clear spots of liquid water. Clouds are made up of billions of droplets air This. So how can we see these drops if they are clear?
The sun will illuminate them with drops of water. The sun emits energy across a fairly broad spectrum, from tiny, dangerous gamma rays to radio waves the size of skyscrapers. But what most likely concerns a small part of the visible spectrum.
The visible spectrum represents solar energy emissions that humans can see. It is made up of colors such as red, orange, yellow, green, blue and purple. When these colors combine, sunlight will appear white.
When white light interacts with cloud droplets, the light is scattered or expelled from the droplets in various directions. This is why the clouds appear white.
So why do clouds turn dark when it rains?
Announcement
Quoted from Science live, rain clouds are gray due to their thickness or height. A cloud becomes denser and denser as it collects more water droplets and ice crystals.
If the clouds are thicker, more light is scattered and the result is less penetration of sunlight. Sunlight plays an important role in changing the color of clouds when it rains
Particles at the bottom of clouds when it rains don’t have as much light to scatter to the human eye. For this reason, the base appears gray when viewed from below, such as from a house or peering through glass.
This effect becomes more pronounced as the size of the water droplet increases. For example, right before the cloud is large enough to fall from the sky To rain or snow. This is because they become more efficient at absorbing light rather than scattering it.
