Waves Problem 2


The above simulation shows disturbances on two identical strings (position is in centimeters and time is in seconds). 


At t=2.5 seconds which of the following is true regarding the superposition of the two waves? Start

  1. Their sum adds up to zero.
  2. Their sum adds up to twice the original waves.
  3. Their sum is as if only one of the original waves is there.
