Waves on a String: Waves on a string are mechanical disturbances that propagate through a stretched string. These can be transverse waves where the displacement is perpendicular to the wave direction. Vibration of a Stretched String: A stretched string vibrates when disturbed, generating waves. The frequency depends on tension, length, and mass per unit length. Stationary (Standing) Waves: Formed by the interference of two waves traveling in opposite directions, creating fixed nod...

Mechanical-Electrical Analogy Mass (m) ⇄ Inductor (L) → Stores energy Damping (b) ⇄ Resistor (R) → Dissipates energy Spring (k) ⇄ Capacitor (C) → Stores potential energy Force (F) ⇄ Voltage (V) → Driving source Velocity (v) ⇄ Current (I) → System response Both follow the same differential equation, making their behavior analogous.

Simple Harmonic Motion (SHM) – Discusses periodic motion, oscillatory systems like pendulums and spring-mass systems, and the differential equation governing SHM. 2. Resonance – Explains how objects vibrate at their natural frequencies under external periodic forces, with examples such as tuning forks, bridge vibrations, and radio tuning. 3. Optics and Lasers – Although not fully visible in the provided text, this section likely covers wave optics, interference, diffraction, and ...
