Your class observes a penny underwater and notices that an
object underwater appears to be closer to the water's surface
than it really is. How do you explain this to the class? -
CORRECT ANSWER-Light bends as it travels from one
substance to another (water to air). This change in the path of
the light wave makes the penny appear closer to the surface than
it really is.
To demonstrate the Doppler effect, you ask a student to stand
still. You tell the student that you will play music from your
phone walking toward him first and then you will hold the
phone out as you walk in a circle around him. Will the sound
increase coming toward him or in a circle? - CORRECT
ANSWER-The student will perceive an increase in the sound's
pitch if the teacher walks toward the student
As the source of the sound moves toward the student, each step
closer (successive sound wave) will start at a point closer to the
student resulting in the sound waves reaching the student with
increasing frequency. Because the frequency of the sound waves
increase, the student perceives an increase in the sound's pitch.
