LAB 1: WAVES INTRO Part A Theory Reference to concepts from Ch15A Waves Power Point slides 8-10 (Q1) and slides 43-70 (Q2 to Q4), please study wave concepts and answer the following questions. 1. What is wave? What is the difference between wave motion and particle in motion? What are the characteristics of mechanical waves? 2. What is sine wave or sinusoidal wave? Write the general form of sine wave and define each term. If y(x, t) = 0.150 sin(20x - 60t) m, find the frequency and speed of this wave. Note: Required to show work. 3. The measurement for sine wave of water, y displacement (water level) as function of time t (x-axis), is shown below. Find the period T based on the information in the Figure below. Calculate the frequency by f = 1/T (Hz). 4. The measurement for sine wave of water, y displacement (water level) as function of position x (horizontal axis), is shown below. Find the wavelength based on the information in the Figure below. Calculate the speed of wave using T from question 3 by = /T. Note: Required to show work. Part B Lab Go to PhET website. Click on Simulation/Physics. Under Physics, choose Sound & Wave. Under Sound & Wave, Waves Intro is the last simulation (Location might change. Sort with A-to-Z search.). Click to run the Waves Intro. Test and understand all functional tools on screen. You must practice figuring out what is the best way to complete the measurement.
