Chapter 15 - Characteristics Of Waves

If you ask a room full of people to picture a wave, they might all think of something different – be it at the ocean, a soundwave, maybe even a person waving. Today we’ll be taking a look at the characteristics of waves, asking you a number of questions regarding how they work.

  • 8. 
    Constructive interference occurs when two waves
    • A. 

      Are traveling in the same direction

    • B. 

      Combine to make a wave with a larger amplitude

    • C. 

      Change their speed and bend

    • D. 

      Combine to make a wave with a smaller amplitude

  • 9. 
    Waves that require a medium to travel through  are called _________________________ waves. 
  • 10. 
    The highest part of a wave is called the ________________________.
  • 11. 
    The bending of waves around the edge of a barrier is known as _____________________. 
  • 12. 
    In standing waves, the ____________________ are points with no amplitude.  (the point where the rope does not appear to move)
