 * __//Think about it//__**
 * The prism reveals that 7 colors of the visible light part of the spectrum. The colors go from red to purple, also the same colors as rainbows.
 * The other kinds of energy that comes from the Sun is UV rays, gamma rays, and radio waves. All the different types of energy are not seen by the naked eye. But special equipment can help show them.-**Shayam Patel**

in 1666 isaac newton found that he could split light into a spectrum of colors. About 10 years later Christian Huygens proposed the idea that light travels in the form of tiny waves.

 * Main Idea:** Electromagnetic Radiation
 * Details:** Violet light is refracted the most because it has the shortest wave length of the entire range of visible light. This work marked the spectroscopy- the science of studying the properties of light. **//Allyson Fancher//**
 * Spectroscopy:** is the study of the properties of light. Studying light has answer questions about energy time, matter, and spcae.
 * Infrared:** radiation recieved as light. Using infrared for x-rays is help for humans and using it for recording motor vehicle speed.
 * Ultraviolet:** this gives you sunburn and is very harmful. -Amani

====**Main Idea: Radio & X-Ray telescopes –** Radio telescopes are instruments used to observe longer wavelenghts of radiation. X ray telescopes are used to dectect stellar and interstellar X ray emission. **Details:** Radio telescopes are collected by satellite dishes. X ray telescopes absorb X rays high above Earths surface. __ //**- Kira Turner**// __====

Electromagnetic radiation was discovered by Isaac Newton in 1966. Electromagnetic radiation is the energy propagated through space by oscillating electric and magnetic fields. It travels at 3x10 to the 8th power m/s in a vacuum and includes (in order of increasing energy) radio, infrared, vivible light (optical) ultraviolet, x-rays, and gamma rays. **Alyssa Walker**
 * 2 column notes E63:**

1. Ranging from red to violet. They grade continuously because its a spectrum. 2. Gamma rays because they are hot, starting at 10 billion k. 3.They use the Spectrum, which is a chart of the entire range of wave lengths of light from an object. 4. Its speed gets added to the speed of the sound, making the wavelength of the sound seem higher to your ear. -**Carlos Davila**

 * Sunspots and Solar Flares –** Sunspots are small dark areas on the sun’s visible surface. A solar flare is an enormous blast of energy from the sun. These are bad for earth’s astronauts and satellites. It also can affect earth. In 1989 a major solar flare created electrical currents that made power outages go out in that area.

1. Positive effects of electromagnetic radiation include taning, and for medical reasons. Taning is caused by UV radiation. Taning is a good thing for somepeople because they believe its helps their overall appearence. Alos, they do not want to be a pale as they are. Also, doctors use X-rays to look at bone fractures. -**Joshua Branker**

 * Digging Deeper:**
 * Main Idea-** In 1666, Isaac Newton found that he could split light into a spectrum of colors.
 * Evidence-** As he passed a beam of sunlight through a glass prism a spectrum of colors appeared from red to violet

__**2 colum notes pg E 67**__ There are many different kinds of spectrums. 2 of which are called the emission spectrum (Bright lines in the stellar spectrum) and the absorption spectrum (dark lines in the stellar spectrum. These spectrums can releave the motion of a star toward or away from earth.- **Angelo Nuni**

The different levels and types of spectrums help show what forms of light and energy are visible to our eyes and exist in our universe-**Andrew Morris** (picture) the purple has the shorter wave lengths and red has the longest.-Arisa Higa

Spectroscopy is the science of studying the properties of a light. People use a spectroscope to to look at the Suns light by separating it into various colors. Each color has a characteristic wavelength. The range of colors from red to violet is called the visible spectrum. -//Andrej Gavric// Geo Words :

1.) Radio telescope – is used when measuring longer wavelengths of radiation 2.) Spectroscopy – the study of light properties and how it interacts with matter 3.) Spectroscope – is used to study the sun’s light by separating it into different colors - Brandy Gibson

Visible light corresponds to a wavelength range of 400 - 700 nanometers and a color range of violet through red. Our eyes are not capable of seeing radiation with wavelengths outside the visible light spectrum. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum. Black is a total absence of light. -Kayleah Beltran

 * 1) Visible specturm: part of the electromagnetic spectrum that is detectable by human eyes.
 * 2) Electromagnetic Radiation: the energy propagated through space by oscillating electric and magnetic fields. it travels at 3x10 8 m/s in a vacuum and includes radio, infared, visible light, ultraviolet, x-rays, and gamma rays.
