Given Solution: ** we know how many wavelength segments will pass every second, and we know the length of each, so that multiplying the two gives us the velocity with which they must be passing ** Your Self-Critique: ok Your Self-Critique Rating: 3 ********************************************* Question: explain how we can reason out that the period of a periodic wave is equal to its wavelength divided by its velocity YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY Your Solution: Once we have determined how far it is between peaks (wavelength) and how fast the wavetrain is passing (velocity), we can then divide the distance between peaks by the velocity to see how much time passes between peaks at a given point. period = wavelength / velocity confidence rating #$&*: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Given Solution: ** If we know how far it is between peaks (wavelength) and how fast the wavetrain is passing (velocity) we can divide the distance between peaks by the velocity to see how much time passes between peaks at a given point. That is, period is wavelength / velocity. ** Your Self-Critique: ok Your Self-Critique Rating: 3 " Self-critique (if necessary): ------------------------------------------------ Self-critique rating: " Self-critique (if necessary): ------------------------------------------------ Self-critique rating: #*&!
