Essential Question How do astronomers use the electromagnetic spectrum to study the universe?
Electromagnetic Spectrum The range of radiant (light) energy arranged in order of wavelength and frequency
Wavelength The distance between to crests of a wave
Frequency A count of the number of crests that pass a point in a given amount of time High frequency = high energy
Radio Waves Transmitted by a radio station Astronomers use them to study what stars are made of, their structure and movement
Microwaves Used to cook your food Used to learn about galaxies Used to learn about stars that are behind clouds of dust
Infrared Waves Used by astronomers to map dust between stars There are 2 types: ○ 1 comes from the heat from the sun ○ 1 is used in any device that has a remote control
Visible Light Rainbows show the different wavelengths of light We are able to see colors of stars which gives us a clue about their temperature Helps us understand the Red Shift and Blue Shift
Ultraviolet Rays Newly formed stars give off UV rays Used to learn about the structure and how galaxies change Causes you to get sunburned
X-Ray Wave Black holes give off X-Ray waves Used in hospitals and doctors offices
Gamma Rays Given off from any explosion like a supernova or a black hole Astronomers use them to gain knowledge of how our universe began and how fast it is expanding
Radio Waves: The Sun
X-Ray: Andromeda Galaxy
Infrared: Constellation Orion
Topic: Electromagnetic Spectrum Essential Question: How do astronomers use the electromagnetic spectrum to study the universe?
WHAT ASTRONOMERS LEARN ABOUT THE ELECTROMAGNETIC SPECTRUM.
White Light & Electromagnetic Spectrum. What is Radiation? Energy that is transmitted from one place to another by electromagnetic waves Heat, UV rays.
The energy that comes from the sun is called electromagnetic radiation. This energy is carried by several waves with different wavelengths and frequencies.
Electromagnetic Waves Waves that DO NOT require a medium to travel Can travel through a vacuum – empty space Waves that carry all types of light energy.
In your own words describe why its better to describe the movement of electrons as an electron cloud rather than orbitals. How do you excite an electron?
Components of the Universe Review REGULAR. List the stages in the life cycle of an Average Star: Nebula – area of dust and gas where stars are formed.
Electromagnetic Energy. Energy Energy is transmitted along waves The sun emits energy in the form of? Electromagnetic waves.
Electromagnetic Spectrum The EM Spectrum What do a radio, heat lamp, the Sun, and an X-ray Machine have in Common? – All four transmit energy.
Light. Properties Light is key to understanding the universe by analyzing light; we learn what planets & stars are made of and their temperature. Light.
The Electromagnetic Spectrum The electromagnetic spectrum includes a wide range of light waves, some that we can't see. Some of the non-visible types of.
Electromagnetic Waves. Electromagnetic Spectrum.
8.5CD Electromagnetic Spectrum and Light Years The student is expected to explore how different wavelengths of the electromagnetic spectrum such as light.
The Electromagnetic Spectrum
THE ELECTROMAGNETIC RADIATION Electromagnetic radiation can be described in terms of a stream of photons, which are massless particles each traveling in.
Electromagnetic Spectrum. Different forms of radiation arranged in order according to their wavelength. – Travels through space at 300,000 km/s or 186,000.
The Electromagnetic Spectrum. There are seven different types of EM waves: Electromagnetic Waves Radio Waves Microwaves Visible Light Infrared Light Ultraviolet.
Chapter 3 Astronomy TEST REVIEW. WHAT ARE ALL THE FORMS OF ENERGY THAT COME FROM THE SUN? Radio waves Microwaves Infrared Rays (Heat) Visible light Ultraviolet.
X-Ray UltravioletVisibleInfraredRadio The Electromagnetic Spectrum and the Universe.
The Electromagnetic Spectrum It’s more than just the rainbow.
Electromagnetic Waves. What are they? Electromagnetic waves are energy which radiate from a source in a wave pattern – troughs and crests Waves can be.
1) wavelength 2) frequency 3) period 4) amplitude 5) energy The distance between successive wave crests defines the ________ of a wave. Question 1.
The Electromagnetic Spectrum The Electromagnetic Spectrum is an arrangement of radiant energy in order of wavelengths and frequencies. It is simply a.
4-1 Radiant Energy. Waves Light travels in Waves similar to ocean waves Light waves are electromagnetic and consist of an electric and magnetic fields.
Waves and the Electromagnetic Spectrum Ch. 17. What is an electromagnetic wave? A transverse wave A wave that consists of vibrating electric and magnetic.
Electromagnetic Spectrum Radio Waves Gamma Rays.

The Electromagnetic Spectrum: Pages 53 and 54 QUESTION: What is a spectrum? OBJECTIVE: Students will be able to name and give a common use of waves that.
Transverse Longitudinal. Why look at waves? Waves are the key to sound and colour. Mobile phone signals, microwave ovens all use energy carried by waves.
Uses of Light Waves. Make a chart using the following categories: Gamma Rays X-rays Ultraviolet Rays Visible Light Infrared Rays Microwaves Radio Waves.
Brain pop. Electromagnetic radiation: Energy that can travel through space in the form of waves. This starts with the longest waves, radio waves, and.
Electromagnetic Spectrum. Radiation – energy moving from a source as a wave.
Electromagnetic Spectrum Unit D: Earth’s Place in the Universe.
ALL ABOUT. Light is a form of energy. –Also known as electromagnetic (EM) radiation. –Carried in small packets called photons. As light wavelength increases,

Electromagnetic Spectrum in Space by Sandy Pope CRMS.
Electromagnetic Spectrum. The electromagnetic spectrum covers a wide range of wavelengths and photon energies.
Electromagnetic radiation waves Waves are three dimensional Waves vibrate in all planes around a center line. The waves have high points called “crests.”
Electromagnetic Waves. Electromagnetic Waves – waves that DO NOT need a medium to travel and carry energy; they can travel through a vacuum (empty space)
Electromagnetic Spectrum. -is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object is the characteristic.
Electromagnetic Waves these are made by vibrating electrical charges that can travel through space where matter is not present They do NOT require matter.
The Electromagnetic Spectrum. In this session we will, Review the electromagnetic spectrum Discuss the various forms of energy represented on the electromagnetic.
What Wavelength Was That? Mr Hemming Examining the Electromagnetic Spectrum with Hands-On Activities.
