Questions & Step-by-Step Solutions

A wave traveling along a string is described by the equation y(x, t) = A sin(kx - ωt). What does the parameter A represent?
  • Step 1: Look at the wave equation given: y(x, t) = A sin(kx - ωt).
  • Step 2: Identify the parameter A in the equation.
  • Step 3: Understand that A is a value that affects the height of the wave.
  • Step 4: Recognize that the amplitude of a wave is the maximum distance it moves from its rest position.
  • Step 5: Conclude that A represents the amplitude of the wave.
  • Amplitude – The maximum displacement of a wave from its equilibrium position.
