ANSWER: Constructive interference Explanation: The amplitudes of in phase points on overlapping waves add up to make a result of a larger amplitude. ANSWER 2: Destructive interference Explanation: The amplitudes of out of phase points on overlapping waves subtract to make a resultant with a smaller amplitude ANSWER 3: Wave interference Explanation: Two waves overlap.
The Richter scale is used, from 0.1 to 9.0 magnitude. The Richter scale is determined from the logarithm of the amplitude of waves recorded by seismographs.
