ملخص الدرس

This lesson explains the mechanics of wave reflection and refraction at media interfaces. It contrasts fixed-end phase inversion (180^{\circ} flip) with free-end reflection, proves that wave frequency is invariant across boundaries (f₁ = f₂), establishes Snell's Law for wave refraction sin θ₁ / sin θ₂ = v₁ / v₂ = λ₁ / λ₂, and applies refraction physics to ocean coastal wave alignment and ripple tank shallow-deep transitions.

• Fixed end reflection causes a 180^{\circ} phase reversal; Free end reflection has no phase shift.
• Refraction is the bending of wave direction caused by a change in wave speed across media.
• Wave frequency f remains strictly constant during refraction across all boundaries (f₁ = f₂).
• Snell's Law of Refraction: sin θ₁ / sin θ₂ = v₁ / v₂ = λ₁ / λ₂.
• Entering a slower medium bends the wave toward the normal and compresses the wavelength (\lambda ∝ v).
• Ocean waves refract parallel to shores because water waves travel slower in shallow water.
