Name: Class: DOPPLER EFFECT-‐Physical Science Text Ch p. 13.10 Doppler Effect-‐Changes in Frequency Due
to Motion AND What is the Doppler Effect Handout
Main Ideas -‐unfamiliar vocabulary -‐proper nouns (names of persons, places or things) -‐key concepts
Details -‐definitions of unfamiliar words -‐information about the nouns; why are they important -‐explanation of key concepts
What is the Doppler effect? What is frequency? How does the number of waves hitting the dock different when a boat is approaching the dock different then when it is moving away? What has to happen in order for the Doppler effect to occur? How are the sound waves changed when the train is approaching you? How is the frequency changed? How is the wavelength change? Copy the picture of the train and label the change to the waves. How are the sound waves from a train changed as the train is moving away from you? (What is the change to wavelength and frequency?) What causes Doppler effect?
Main Ideas -‐unfamiliar vocabulary -‐proper nouns (names of persons, places or things) -‐key concepts

What is red-‐shift for stars? What did astronomers find when looking at galaxies? What is happening to the universe? How do we know?
Summary: Review your notes. What were you supposed to learn about the Doppler effect? Restate the main ideas in your own words.
