The Rainbow
Storyboard Text
- HI! I'm Keziah Teodosio.
- Do you look up in the sky after the rain stops and see a rainbow? And starts wondering why is there are many colors in a single rainbow?
- In this comic, I will explain the formation of the rainbow using the concept of wavelength and frequency of visible light.
- Rainbows are the result of the refraction and reflection of light. Both refraction and reflection are phenomena that involve a change in a wave's direction. A refracted wave may appear curved, while a reflected wave might seem to "bounce back" from a surface or other wavefront.
- A rainbow shows up as a spectrum of light: a band of familiar colors that include red, orange, yellow, green, blue, and violet. The name "Roy G. Biv" is an easy way to remember the colors of the rainbow and the order in which they appear: red, orange, yellow, green, blue, indigo, and violet.
- Red has the longest wavelength of visible light, about 650 nanometers. It usually appears on the outer part of a rainbow's arch.
- Violet has the shortest wavelength (about 400 nanometers), and it usually appears on the inner archway of the rainbow.
- At their edges, the colors of a rainbow actually overlap. This produces a sheen of "white" light, making the inside of a rainbow much brighter than the outside. Visible light is only part of a rainbow. Infrared radiation exists just beyond visible red light, while ultraviolet is just beyond violet. There are also radio waves (beyond infrared), x-rays (beyond ultraviolet), and gamma radiation (beyond x-rays). Scientists use an instrument called a spectrometer to study these invisible parts of the rainbow.
- Now that I'm done, I need to go now. Thank you and have a nice day
