Show students the graphic on the electromagnetic spectrum shown to the right. Have them write for five minutes in their journals about the graphic. Tell them to think about the relationships in and among the various wavelengths and the position of each type of radiation in the electromagnetic spectrum. Explain to your students that the visible light from the Sun is actually composed of the colors red, orange, yellow, green, blue, indigo, and violet, which can become distinguishable when sunlight passes through a prism.
A good way to remember the order of the colors is to note that the first letters of the colors spell out the name ROY G. We can think of light traveling in waves with properties of wavelength and frequency. Wavelength is the distance between identical locations on adjacent waves.
The illustration below may help your students see what wavelength is for a given wave. Diagram showing what wavelength is for a wave. Tells students that frequency is the number of complete waves, or wavelengths, that pass a given point each second.
Note: Use yellow sparingly. Too much yellow can actually send the opposite message. Too much yellow causes people to feel judgmental and critical. Located in the middle of the rainbow, green is the color of life. Here in the West, it is also a color symbolizing wealth, which is why our money is green. But green is also a bit of a dichotomy.
On one hand, green represents life and growth; on the other hand, it represents envy. Ever heard the phrase green with envy? Because so much of our plant life is green, this color is often linked to nature and living naturally. Interestingly, the human eye is capable of distinguishing more variations of the color green than any color in the rainbow. The color of the sky and the ocean, blue represents peace, relaxation, and stability.
This is no surprise. When people want to relax, they often seek out water. Even just changing out the wallpaper on a computer background to an ocean scene can be beneficial in this regard. Because blue is the color of the heavens, it is often associated with divinity and is used to illustrate trust and loyalty.
The Blues is a famous music genre that originated in the deep south and is characterized by mellow sounds. Note: Too much blue can make people feel rigid. Blue is a good color to include in moderation. Indigo is the most disputed color in the rainbow. Is indigo truly deserving of its own place, or are people simply seeing blue and violet?
Along the same lines, people have long tried to answer this question: Is indigo blue or purple? Although, if you want to get more specific, indigo is three-quarters blue and one-quarter purple.
A mix of purple and blue, indigo is the color of the midnight sky. Because of this, indigo encourages individuals to think more deeply about life and has strong connections to spiritualism and inward thinking.
Too much indigo results in a person feeling intolerant, judgmental, and avoidant. Too much inward thinking can result in frustration or angst.
Used in moderation, however, indigo can be very useful. This discrepancy puts some beams out of sync and some beams in sync, causing them to cancel each other out or reinforce each other. Thus, brightness alternates with emptiness. Supernumerary bows are easiest to produce with a misting hose, whose drops are very similar in size. Supernumerary bows appear as extra bands alongside the main rainbow. Contrary to an often repeated belief, rainbows are not usually complete circles whose other halves are hidden by the horizon.
In fact, a rainbow cannot exist without a beholder. Any rainbow that appears at 42 degrees from the antisolar point will disappear into the ground unless you are well above the surface of the earth. You have much better chances of spotting a glory — a spectrum forming a ring 5 to 10 degrees from the antisolar point — from an airplane passing over a layer of clouds, or from the rim of a canyon filled with fog.
Glories can also appear in concentric multiples, like bullseyes. Well, that depends on your culture. Several myths around the world interpret rainbows as bridges. A famous rainbow bridge, Bifrost of Norse mythology , stretches from Earth to Asgard where the vigilant, far-seeing Heimdall guards the realm of the gods against invading giants and demons. Double rainbows, what do they mean? This man's fascination with the rare phenomenon went viral on the Internet in That Iris herself, the Greek god who personifies the rainbow, functioned more as a messenger than a weather-maker, speaks to the ability of the rainbow to link disparate worlds.
In other mythologies, the rainbow spanning the sky is a monstrous snake. The Australian rainbow serpent controls rains and monsoons, sucking up and expelling water and retreating to deep waterholes during drought.
Similarly, the Ewe peoples of West Africa imagine the rainbow as a serpent that stretches across the sky to drink from the other side of the world.
The Shoshoni in North America also tell of a rainbow snake who scratches his back against the firmament, dislodging pieces of ice and precipitating the weather. And the Semang of Malaysia consider the rainbow a python that infects the earth it touches. Others interpret the rainbow as a sign of good fortune. According to a medieval Germanic belief, no rainbow can appear for 40 years before the end of the world, so the sight of any rainbow again reassures humanity that the apocalypse is not impending.
Some Mojave of Arizona believe that a violent storm will end when every colour of the rainbow appears. And of course, the end of the rainbow has been supposed to hide all kinds of treasures, like magic pearls, precious beads, magical golden dishes, and gold coins. Yet some see the rainbow as an ill omen.
The Nias people of Indonesia fear the rainbow, a giant net spread by a malevolent spirit to catch souls. In Slavonic tales, a fey being sits at the foot of the rainbow, combing her hair, and her glance brings death.
Many cultures hold that pointing at a rainbow provokes curses; according to Hungarian folk belief, your finger will wither, and a Chinese text says your hand will ulcerate. The Sumu of Honduras and Nicaragua hide their children indoors at the appearance of a rainbow. Some even perform rituals to make a rainbow go away.
Children in Staffordshire, England, have been known to cross a pair of sticks and place a stone on top of them to this end. Oshumare — a rainbow god from Togo and the Volta region of Ghana — spends half the year as a hunter and half the year as a mermaid. Rainbows also wield power over gender. In the folklore of several Eastern European countries, anyone who passes under the arch will change sexes.
Relatedly, many rainbow deities are androgynous, split into male and female aspects — red versus violet or primary rainbow versus secondary rainbow — or attracted to the same sex. The androgynous West African god and rainbow serpent Oshumare spends half the year as a hunter and half the year as a mermaid.
Rainbow gods like the gender-fluid Aido Hwedo of Vodou belief have also influenced contemporary culture, showing up in the poetry of lesbian writer Audre Lorde. Perhaps not surprisingly, rainbow flags have become a symbol of pride for the LGBTI community, first appearing as such in when designed by San Francisco artist Gilbert Baker.
