Questions & Step-by-Step Solutions

A wave on a string is described by the equation y(x, t) = 0.1 sin(2πx - 4πt). What is the amplitude of the wave?
  • Step 1: Look at the wave equation given: y(x, t) = 0.1 sin(2πx - 4πt).
  • Step 2: Identify the part of the equation that is multiplied by the sine function.
  • Step 3: The coefficient of the sine function is 0.1.
  • Step 4: This coefficient represents the amplitude of the wave.
  • Step 5: Therefore, the amplitude of the wave is 0.1 meters.
  • Wave Properties – Understanding the characteristics of waves, including amplitude, wavelength, frequency, and wave speed.
  • Mathematical Representation of Waves – Interpreting wave equations in the form of y(x, t) = A sin(kx - ωt) to extract physical properties.
