How Rainbows Are Formed

Compartilhar

Rainbows are one of nature’s most beautiful displays. Have you ever been curious about the science that creates them? A rainbow forms when sunlight passes through raindrops in the sky. The light bends, or refracts, as it enters each drop, splitting into different colors. These colors reflect off the inside of the raindrop and bend again as they exit, creating a spectrum in the sky. This bending process is what gives us the beautiful arc of colors we see after a rain shower.

The colors in a rainbow always appear in the same order: red, orange, yellow, green, blue, indigo, and violet. This sequence is known as the spectrum . Each color represents a different wavelength of light, with red having the longest wavelength and violet the shortest.

Interestingly, no two people see the exact same rainbow. This happens because each person’s viewing angle is slightly different. So, next time you see a rainbow, remember that you’re seeing a unique display created just for you!

Palavras Difíceis: Refract (bend or change direction when entering a new medium; dobrar ou mudar de direção ao entrar em um novo meio), Spectrum (a range of colors; uma variedade de cores).
