EN-Test: The Magic of the Rainbow – an explaining of a natural phenomenon

The Formation of a Rainbow

A rainbow is one of the most fascinating phenomena in nature. It occurs when sunlight hits raindrops and is refracted, reflected, and refracted again. This interaction causes the light to split into its constituent colors, forming a vibrant arc in the sky. The basic colors of the rainbow are red, orange, yellow, green, blue, indigo, and violet.

The angle at which light is refracted is about 42 degrees from its original direction. Therefore, a rainbow is seen when the sun is behind the observer and rain clouds are on the horizon. The perfect combination of light and water droplets creates this impressive spectacle.

Significance and Symbolism of the Rainbow

A rainbow holds not only scientific significance but also rich symbolism. In many cultures and myths, the rainbow represents hope, peace, and a connection between heaven and earth. In modern times, the rainbow has gained strong symbolic importance as a sign of diversity and acceptance. The LGBTQ+ community has adopted the rainbow as a symbol for their movement to celebrate and protect the diversity and rights of all individuals.

Interesting Facts About Rainbows

• A rainbow is always a circle, but from the ground, only part of it is usually visible.
• Double rainbows occur when light is reflected twice inside the raindrops. The second arc is fainter and has reversed colors.
• Rainbows can also appear at night and are called moonbows. These are often fainter and less colorful.
• Sometimes, rainbows can be seen in waterfalls or the mist of the ocean.
