PROSES TERJADINYA PELANGI

Summary

In this video, viewers are introduced to the phenomenon of rainbows and the science behind them. The sunlight, which is polychromatic, contains multiple colors. When sunlight passes through raindrops, it undergoes refraction, causing the light to break into its individual colors, forming the rainbow. The spectrum includes red, orange, yellow, green, blue, indigo, and violet. This colorful display can also occur near waterfalls where water droplets scatter sunlight. The video explains the process in an engaging and educational manner, encouraging viewers to understand the natural beauty of rainbows.

Q & A

What is the main cause of the rainbow phenomenon?

The rainbow occurs due to the refraction of sunlight by raindrops, which breaks down white light into a spectrum of colors.

What type of light does the sun emit?

The sunlight is polychromatic, meaning it consists of many different colors.

What is the composition of white sunlight?

White sunlight is a combination of light with different wavelengths, which corresponds to various colors.

How many colors can the human eye perceive in sunlight?

The human eye can perceive seven colors within the sunlight spectrum.

What is refraction?

Refraction is the process in which light bends as it passes through a different medium, causing the light to split into its component colors.

What happens when sunlight passes through rainwater?

When sunlight passes through raindrops, the light is refracted and split into a spectrum of colors, creating a rainbow.

What colors are visible in a rainbow?

The visible spectrum of a rainbow consists of red, orange, yellow, green, blue, indigo, and violet, which can be remembered by the acronym 'MEJIKUHIBINIU.'

What does the acronym 'MEJIKUHIBINIU' represent?

'MEJIKUHIBINIU' represents the colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet.

Can a rainbow occur in places other than after rain?

Yes, a rainbow can also appear near waterfalls, where the water spray can serve as the medium to refract sunlight.

Why is it possible to see a rainbow after it rains?

It is possible to see a rainbow after rain because raindrops act as the medium that refracts sunlight, allowing the colors to separate and form a rainbow.
