TRANSCRIPT

  • Topic: Electromagnetic SpectrumEssential Question: How do astronomers use the electromagnetic spectrum to study the universe?

  • Topic: Electromagnetic SpectrumEssential Question: How do astronomers use the electromagnetic spectrum to study the universe?

    Electromagnetic SpectrumThe range of radiant (light) energy arranged in order of wavelength and frequency

  • Topic: Electromagnetic SpectrumEssential Question: How do astronomers use the electromagnetic spectrum to study the universe?

    WavelengthThe distance between two crests of a waveFrequencyA count of the number of crests that pass a point in a given amount of timeHigh frequency = high energy

  • Topic: Electromagnetic SpectrumEssential Question: How do astronomers use the electromagnetic spectrum to study the universe?

    Radio WavesAstronomers use them to study what stars are made of, their structure and movementMicrowavesUsed to cook your foodUsed to learn about galaxiesUsed to learn about stars that are behind clouds of dust

  • Radio Waves used to look at the Sun

  • Topic: Electromagnetic SpectrumEssential Question: How do astronomers use the electromagnetic spectrum to study the universe?

    Infrared WavesUsed by astronomers to map dust between starsVisible LightRainbows show the different wavelengths of lightWe are able to see colors of stars which gives us a clue about their temperatureHelps us understand the Red Shift and Blue Shift

  • InfraredVisible Light

  • Topic: Electromagnetic SpectrumEssential Question: How do astronomers use the electromagnetic spectrum to study the universe?

    Ultraviolet RaysUsed to learn about the structure and how galaxies changeX-Ray WaveUsed to detect black holes because black holes give off X-Ray waves

  • Topic: Electromagnetic SpectrumEssential Question: How do astronomers use the electromagnetic spectrum to study the universe?

    Gamma RaysGiven off from any explosion like a supernova or a black holeAstronomers use them to gain knowledge of how our universe began and how fast it is expanding

  • Now take some timeTake 2 minutes to go over your notes and highlight or underline the main ideas that answer the essential question, you should not highlight everything:Essential Question: How do astronomers use the electromagnetic spectrum to study the universe?

  • Time to use the left hand columnYou will now write your own questions using the verbs provided.
