ملخص الدرس

This lesson introduces the universal physics of wave propagation as energy transmission without bulk mass transport. It categorizes waves as transverse vs longitudinal and mechanical vs electromagnetic, establishes the wave speed equation v = f \lambda, explains how to extract wavelength from (y-x) graphs and period from (y-t) graphs, and applies wave principles to seismic P and S earthquake waves.

• A wave transfers energy and momentum without transporting matter.
• Transverse waves oscillate perpendicularly (crests and troughs); Longitudinal waves oscillate parallel (compressions and rarefactions).
• Electromagnetic waves propagate through a vacuum at c = 3 × 10⁸ \frac{m}{s}; Mechanical waves require a medium.
• Fundamental wave equation: v = f * \lambda = \\frac{lambda}{T}.
• Wave speed is a property of the medium; for a given medium, frequency and wavelength are inversely proportional.
• Displacement–position (y–x) gives wavelength \lambda; Displacement–time (y–t) gives period T.
