Wave properties definitions and examples

📚 Quick Study Guide

• 📏 Wavelength: The distance between two successive crests or troughs of a wave. Symbol: $\lambda$ (lambda).
• 📈 Amplitude: The maximum displacement of a point on a wave from its equilibrium position.
• ⏱️ Period: The time required for one complete cycle of a wave to pass a given point. Symbol: T.
• frequency Frequency: The number of complete cycles of a wave that pass a given point per unit time. Symbol: f. Measured in Hertz (Hz). $f = \frac{1}{T}$
• 🚀 Wave Speed: The speed at which the wave propagates through a medium. Formula: $v = f\lambda$
• 🌊 Transverse Waves: Waves in which the displacement of the medium is perpendicular to the direction of propagation (e.g., light waves, waves on a string).
• 🔊 Longitudinal Waves: Waves in which the displacement of the medium is parallel to the direction of propagation (e.g., sound waves).
• 🪞 Reflection: The bouncing back of a wave when it strikes a boundary.
• refract Refraction: The bending of a wave as it passes from one medium to another.
• ➕ Superposition: The phenomenon where two or more waves overlap and their amplitudes add together.
