The students in the diagram are communicating with the cans and string.Which is the most likely explanation of how the students can hear and communicate using the objects?
  • A Mechanical Wave transfers sound through the string
  • sound bounces off the can and echoes
  • sound travels through the string as an electromagnetic wave

  • space
  • rock
  • air
  • water
As the fire truck approached Mary, the pitch of the siren got higher. Once the fire truck passed and moved away, the siren's pitch got lower. This change in pitch is because of a change in the sound wave's
  • concussion.
  • amplitude.
  • reflection.
  • frequency.
What does pitch depend on?
  • amplitude
  • frequency
  • intensity
  • volume of sound
