Mini-Quiz: Conventions for Doppler Effect Equations

1. Why should there be a convention in direction of motion?

   To add to things you must rememberSorry, not correct. Try another button. It really is not necessaryGood try, but not right. Select another answer. To avoid confusion in equationsThat is correct. You understand about the equation conventions.

2. Why is there a restriction that the velocity of the source is less than the wave velocity?

   The Doppler Effect does not work at velocities greater than wave velocityCorrect. You are smart! The restriction is to make the equations easier to memorizeOops! Wrong answer. Re-read the question and try again. No one is really sure why there is such a restrictionSorry, not correct. Try another button.

3. What is the unit for the period of a wave?

   HzOops! Wrong answer. Re-read the question and try again. MetersGood try, but not right. Select another answer. SecondsThat is correct. You understand about the equation conventions.
