Lecture 26: Wave motion

Objectives: In this lecture, students will learn to
  • distinguish between transverse and longitudinal waves
  • analyze traveling waves in terms of wave length, frequency, and wave speed
  • distinguish between wave speed and transverse speed
  • relate the speed of a wave on a string to properties of the string
  • solve problems involving the Doppler effect
