Step-by-step explanation:
the amplitude is the height of the wave.
like with sound - the further away you are, the lower the volume of the sound (as the sound volume is the indicator of the amplitude of a sound wave, or the brightness of a light is the indicator of the amplitude of a light wave).
the same for any other type of wave (like the seismic wave of an earthquake).
so, the larger the distance, normally the smaller the amplitude.
The answer she has is not correct.
All the steps she did are correct, except they forgot to convert the decimal answer into the proper percentage by multiplying it by 100.
The correct answer should be 0.125 * 100 = 12.5%
Answer:
Least: 10.5
Greatest: 14.125
Hope that helps!
