  • If the frequency of a wave decreases, what will the energy do?
    The energy will decrease.
  • What is destructive interference?
    When the crest of one wave and the trough of another overlap. They cancel each other out
  • What are the 4 types of wave interaction?
    1. Reflection, 2. Refraction, 3.Diffraction, 4. Interference
  • What is wave interference?
    When 2 or more waves overlap.
  • What is reflection?
    When a wave bounces back after hitting a barrier. ex. light off of snow
  • What is the wavelength of a wave?
    The distance between 2 crests or 2 troughs
  • What do waves transfer or give off?
    Energy
  • What are examples of a medium?
    liquid, solid, or gas
  • What is constructive interference?
    when 2 wave crests or roughs overlap. Results in a larger amplitude and has more energy.
  • What is the amplitude of a wave?
    It is the wave height, measured from the resting position to either the trough or the crest.
  • When a wave moves, does the material travel? ex leaf in water
    no. The material does not move, the water does.
  • What is wave Diffraction?
    The bending of waves around a barrier
  • What is an example of a mechanical wave?
    light waves, sound waves, and ocean waves
  • What is wave refraction?
    The bending of a wave when it passes through a medium
  • Where is the crest of a wave located?
    The very top of the wave. The highest point.
  • Where is the trough of a wave?
    The lowest point of the wave
  • What are the 2 different types of Wave Interference?
    Constructive and destructive
  • What is a wave?
    any disturbance that transits energy thought matter or empty space
  • What kind of waves need a medium to travel through?
    A mechanical wave
  • What is the frequency?
    The number of waves produced in a given time.
  • How is energy transferred from a wave?
    The vibrations of particles in the medium
  • How would you measure a wavelength?
    measure the distance between the same point on 2 waves
  • What is this an example of?
    Refraction
  • When a wavelength decreases, what happens to the frequency?
    The frequency will increase.
  • How does the moon shine at night when there is no light?
    The sunlight reflects off of the moon.
