Is it possible to predict when a `rainbow` will occur?

Weather of Arabia - The rainbow is one of the most beautiful scenes that can be seen after the rain, as it decorates the sky with its seven amazing colors, but have you ever wondered why we don't always see the rainbow after the rain? And can the weather forecaster tell when the rainbow will appear? Read on to find out!

How does the "rainbow" phenomenon occur?

Although light may appear white to you, it is actually made up of different waves, each wave of light having a different color, and traveling at a different speed. (The seven colors of the rainbow are: red, orange, yellow, green, blue, indigo (dark blue), and violet (purple)).

But because light travels so fast, you can't see the separate colors, so if you want to see the different colors that are in the light, we need to slow it down.

But how do you slow down the light? Generally, light travels in a straight line. One way to slow down light is to make it pass through a transparent object, such as water droplets.

So the rainbow phenomenon occurs when sunlight passes through raindrops or water spray, so the white sunlight is divided into the seven colors of the spectrum as a result of the refraction of these rays inside, then these rays are reflected and reappear outside the drop at different angles, depending on its color (and its wavelength). ), so the visibility of a rainbow depends on where you stand in relation to the sun and raindrops.

Can a weather forecaster predict a rainbow?

A weather forecaster can predict weather conditions such as clouds and rain that create the conditions for a rainbow, but they can't tell if you'll be in the right place to see it, because seeing a rainbow depends on where you stand in relation to the sun and raindrops (as mentioned earlier).

Why don't we always see rainbows after it rains?

We only see a rainbow after it rains when the sun appears from among the clouds, with a lot of water still in the air, the sun's rays pass through the water droplets, causing the light to be refracted, and then you can see all the separate colors forming a rainbow in the sky !
