Rainbows often appear after rain when the sky is clear. It\u2019s a shimmering band of colors in the sky, like a giant bridge painted by light. But do you know why the rainbow has 7 colors? How Is a Rainbow Created? Let\u2019s discover this secret together with I-CLC!<\/span><\/i><\/p>\n

Rainbows form when sunlight passes through tiny raindrops in the air. These raindrops act like small prisms, splitting sunlight into many different colors. This scientific phenomenon is called <\/span><\/i>light dispersion<\/i><\/b>.<\/span><\/i><\/p>\n

When sunlight enters a raindrop, it bends\u2014a process called <\/span><\/i>refraction<\/i><\/b>. The light then reflects inside the raindrop and bends again as it exits. The result is that white sunlight is split into the 7 colors we see in a rainbow.<\/span><\/i><\/p>\n
