Physics 7C DLM 02 OverviewDLM 02Model: Plane Waves Act 8.1.3 Representing a 1-D Harmonic Wave Graphically (~90 min)Learning Goals: • Understanding that the displacement of the medium when a harmonic wave is present depends on two parameters: position and time • Understanding that it takes two graphs, one as displacement of medium vs. time and one as displacement of medium vs. distance to completely represent a wave graphically • Understanding that the graph of a harmonic wave as a function of either position or time is sinusoidal (i.e., corresponds to a sine or cosine function) • Understanding that it takes a mathematical function of two variables (e.g., y and t) to represent a wave (i.e., a wave function) Act 8.1.4 Waves and the Wave Equation (~50 min)Learning Goals: •Solidify ideas about wave parameters and graphing waves •Understand that y(x,t) - y0=Asin 2πtT±2πxλ+φ⎛ ⎝ ⎜ ⎞ ⎠ ⎟ =AsinΦ(x,t)is the 1-D harmonic wave function and that when graphed as a function of either x or t, while holding the other variable constant, a sine wave results. •Begin understanding the total phaseΦ(x,t) Reading Assignment •Read the first portion of the 7C Course Notes on Waves.
