This is Not a Rainbow

The video explores the colors of the rainbow, focusing on the historical and scientific perspectives. It discusses Isaac Newton's original color labeling, the absence of purple in rainbows due to the separation of red and blue light, and how optical illusions and supernumerary rings can create the appearance of purple in rainbows.

What was the reason Isaac Newton included indigo in his list of rainbow colors?

• To match the number of colors with the number of planets

• To align with the number of notes in the musical scale

• Because indigo was his favorite color

• To make the rainbow more colorful

Why do purple, magenta, and hot pink not appear in a prism-created rainbow?

• They are absorbed by the prism

• They are not part of the visible spectrum

• They are too faint to be seen

• They require a combination of red and blue light

What is the main reason violet is present in a rainbow but purple is not?

• Violet is a primary color

• Violet is brighter than purple

• Purple is a mix of red and blue, which are on opposite sides of the rainbow

• Purple is absorbed by water droplets

What causes the appearance of purple in some rainbows?

• The overlap of red and violet supernumerary rings

• The reflection of sunlight

• The presence of large raindrops

• The scattering of light by dust particles

How do supernumerary rainbows form?

• Through the refraction of light in large raindrops

• From the scattering of light by clouds

• By the interference of light waves in small raindrops

• Due to the reflection of light on the ground
