    G4 gravel
  • The highest point of this transverse wave is the ____.

    refraction
  • True or False: A wave with more amplitude will have less energy going through it
    false
  • True or False: Our test is on the computer
    true
  • True or False: the more density an object has, the faster sound will travel through it.
