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?

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?
