SUMMARY

The discussion centers on the reflection of a wave from a fixed end, specifically analyzing the wave equation y=2 sin(4x-8t) and its reflected counterpart. The correct reflection of a wave traveling to the right is y=-2 sin(4x+8t), which indicates both inversion and direction change. Key concepts include the properties of sine functions, the significance of negating the entire wave function, and the standard form of wave equations. Misunderstandings arose regarding the application of reflection coefficients and boundary conditions.

PREREQUISITES
  • Understanding of wave equations, specifically y=A sin(wt-Kx)
  • Knowledge of wave reflection principles at fixed boundaries
  • Familiarity with trigonometric identities, particularly for sine functions
  • Basic grasp of wave properties, including amplitude, frequency, and phase
NEXT STEPS
  • Study wave reflection and transmission at boundaries in greater detail
  • Learn about the derivation and application of reflection coefficients
  • Explore the implications of wave inversion in physical systems
  • Investigate the use of trigonometric identities in wave superposition
USEFUL FOR

Students and professionals in physics, particularly those focusing on wave mechanics, acoustics, and engineering applications involving wave behavior and reflection.

And notice that after that the OP disappeared. Once he knew he'd made the right answer he lost interest.
actually i disappeared cuz i asked the question a day before my exam and didnt have the time to read all the replies.

thanks for the help everyone
