Wave BasicsName:© The Physics Classroom, 2009Page 1Wave SpeedRead fromLesson 2of theWaveschapter atThe Physics Classroom:MOP Connection:Waves: sublevels 3 and 41.A physics teacher attaches a slinky to the wall and begins introducing pulses with differentamplitude. Which of the two pulses below will take the least amount of time to reach the wall?Justify your answer:2.The physics teacher then begins introducing pulses with a different wavelength. Which of the twopulses below will take the least amount of time to reach the wall?Justify your answer:3.Stan and Anna are conducting a slinky experiment. They are studying the possible effect of severalvariables upon the speed of a wave in a slinky. Their data table is shown below. Fill in the blanks inthe table, analyze the data, and answer the following questions.MediumWavelengthFrequencySpeedZinc, 1-in. dia. coils1.75 m2.0 HzZinc, 1-in. dia. coils0.90 m3.9 HzCopper, 1-in. dia. coils1.19 m2.1 HzCopper, 1-in. dia. coils0.60 m4.2 HzZinc, 3-in. dia. coils1.82 m2.2 HzZinc, 3-in. dia. coils0.95 m4.2 HzRyan
