Waves and motion!

Types of Waves:

1. Mechanical Waves: require a medium (solid, liquid, gas)
   • Longitudinal Waves (compression)
   • Transverse Waves (perpendicular)
2. Electromagnetic Waves: no medium required
   • Radio Waves
   • Microwaves
   • Infrared Radiation
   • Visible Light
   • Ultraviolet Radiation
   • X-rays
   • Gamma Rays

Wave Motion:

1. Frequency (f): oscillations per second (Hz)
2. Wavelength (λ): distance between two consecutive peaks/troughs (m)
3. Speed (v): distance traveled per second (m/s)
4. Amplitude (A): maximum displacement from equilibrium
5. Period (T): time for one oscillation (s)

Wave Equations:

1. Wave Equation: ∂²u/∂t² = c²∇²u
2. Frequency-Wavelength Relation: f = c/λ
3. Speed-Frequency Relation: v = λf

Types of Motion:

1. Simple Harmonic Motion (SHM)
2. Damped Motion
3. Forced Motion
4. Resonance
5. Oscillations

Real-World Applications:

1. Sound Waves: music, speech, ultrasound
2. Light Waves: vision, optics, communication
3. Water Waves: oceanography, surfing, shipping
4. Seismic Waves: earthquake science, geology
5. Medical Imaging: MRI, CT scans

Key Concepts:

1. Wave-Particle Duality
2. Interference
3. Diffraction
4. Refraction
5. Reflection
