Answer

Brief Explanations:

  • Destructive interference: When two waves meet and cancel each other out, their amplitudes subtract. For example, if one wave has an amplitude of (A) and the other has an amplitude of (-A) (opposite in phase), the resultant amplitude is (A+(-A) = 0).
  • Constructive interference: Occurs when two waves add up to form a wave with a larger amplitude. If two waves have amplitudes (A_1) and (A_2), the resultant amplitude is (A_1 + A_2) (when in - phase).
  • Reflection: Is the bouncing back of a wave when it hits a boundary. For example, light reflecting off a mirror or sound reflecting off a wall.
  • Refraction: Is the bending of a wave as it passes from one medium to another. This is due to a change in the wave's speed. For example, light bending when it goes from air to water.
