Colors of the Rainbow Trivia Quiz

Answer: red

Red is the first (outermost) and top color in a rainbow because it has the longest wavelength of visible light. This allows it to bend the least when refracted by water droplets. This causes it to appear at the top of the rainbow arc. It is refracted the least. That is why when a baby is just a few weeks old, they're able to recognize red first because red has a long wavelength that is able to reach their vision first.

The other colors are shades of blue.

Answer: orange

Orange has its own specific wavelength of light, and appears in a rainbow due to the way light bends at different angles based on its wavelength. It is said that Sir Isaac Newton initially identified five colors of the rainbow, but wanted to add two more.

He later included orange as one of them. He wanted the seven colors of the rainbow to align with the seven notes of the musical scale. The other colors are shades of green. The wavelength of orange light is approximately 590-620 nanometers (nm).

Answer: Yellow

Yellow is the second primary color in a rainbow, and the third color overall. Yellow is the most common color of the rainbow at sunrise and sunsets because sunlight travels a longer path through the atmosphere and, when it does so, it scatters shorter wavelengths of light, like blue and green, away from our line of sight.

This leaves the longer wavelengths, yellow, orange, and red,-to reach our eyes, creating the sunset or sunrise rainbow effects.

Answer: Green

The colors of the rainbow are always in the same order. Green is the fourth color from the top of the rainbow. With three colors on each side of green, it sits perfectly in the center of the seven-color spectrum.

Green is a secondary color in the traditional subtractive color model for paint and pigment.

Answer: blue

Blue represents calmness and serenity. It is the fifth color of the light spectrum. In culture blue equates to God-sent peace. It is one of the five primary colors. The wavelength of blue light is generally between the 380 and 500 nanometers (nm) range. Blue is one of the first colors Newton described as part of the rainbow.

It is said that scholars have noted that during Newton's time he regarded the color at the time known as "blue" was actually cyan, and what Newton called "indigo" would today be called blue.

Answer: Indigo

The wavelength of indigo light is approximately 420 to 450 nanometers. system, the indigo arc is the Its position in the spectrum is between blue light (450-490 nm) and violet light (400-420 nm). Indigo is a bluish dye, and was a major cash crop in the Americas from the 1700s.

Ivory is an off-white color with a subtle yellowish or creamy tint, which reminds people of the natural color of elephant tusks. Iron, when pure and metallic it is typically a silvery-gray color. Indochine is a bright and light shade of orange.

Answer: violet

Violet is a name of a plant also known as a viola. It is the color of a rainbow inside the rainbow's arc. It is between blue and the end of the visible spectrum. The wavelength of violet light is in the range of 380 to 450 nanometers.

The "color" of vanilla usually refers to a range of colors. It can be a light, creamy, off-white shade with a hint of yellow and can sometimes refer to the rich, dark brown of the vanilla bean itself.
Viridian is a blue green pigment. it comes from the Latin word for green, "viridis". Verdigris refers to the greenish-blue patina that forms on copper, bronze, and brass.

Answer: False

Purple IS made from the mixture of red and blue light, but these colors are at opposite ends of the color spectrum. It doesn't exist in a rainbow because it is not a single wave of light, but two colors.

Violet is the spectral color that has the shortest wavelength visible to the human eye that is a shade of the color purple.

Answer: False

Black is not part of the rainbow because black is the absence of light, which means the first part of the statement is true. However, it is possible to see a rainbow at night. What makes it confusing is that the rainbow that comes off of the moon is much paler and less colorful than a daytime rainbow produced by the sun.

The light source at night is the moon, while the water source comes from water particles. They are called lunar rainbows or moonbows.

Answer: low altitude angle

A low sun altitude angle is essential for a rainbow to be visible because the rainbow's height is inversely related to the sun's angle, meaning, the lower the sun, the higher the rainbow's arc. When the sun sits low in the sky at less than 42 degrees above the horizon, the rainbow is higher and is seen better. When the sun is higher a rainbow is positioned lower.

A low-magnitude angle is a small angle, typically less than .26 radians, and is often used in the small-angle approximation.

A low aptitude angle is not a standard used term, just made for this question. A low latitude angle relates to a low angle of incidence for solar radiation. This means the sun's rays hit the Earth's surface at a more oblique angle. Lower latitude regions that are closer to the equator, receive sunlight at a high angle, concentrating the energy and leading to warmer climates.
