• What Are the Applications of the Wave Equation?
  The wave equation models how disturbances travel. Explore its uses in strings, sound, light, water, and seismic waves, with a worked string example.
• What Is the Difference Between a Particle and a Wave?
  A particle is localized; a wave is a spreading disturbance. Learn the classical difference and why quantum objects show both particle-like and wave-like behavior.
