This video introduces oscillations, including amplitude, frequency, period, and angular frequency. It also explains phase and path difference, laying the foundation for wave coherence and interference.

This video explains the conditions for simple harmonic motion and explores pendulums and mass-spring systems. It includes key formulas for period and angular frequency.

This video explores velocity, acceleration, and energy transformations in simple harmonic motion. It includes graph interpretation and the relationship between displacement, velocity, and acceleration.

This video introduces trigonometric equations for displacement, velocity, and acceleration in SHM, including phase relationships and maximum values. It also covers energy calculations for kinetic, potential, and total energy in oscillating systems.

This video introduces travelling waves, comparing transverse and longitudinal waves. It also covers electromagnetic waves, the electromagnetic spectrum, and why sound cannot travel through a vacuum.

This video explains wave intensity and how it relates to amplitude and distance. It also introduces interference and the principle of superposition with constructive and destructive examples.

This video covers polarization of transverse waves, describing types of polarized light and how polarizers and analyzers work. It introduces Malus’s and Brewster’s laws and their effect on intensity.

This video introduces ray and wavefront diagrams and explores how they help us understand wave phenomena like reflection, comparing perfect and diffuse reflection across different wave types.

This video explains how waves change direction at boundaries due to differences in medium density, introduces Snell’s Law, and covers critical angle and total internal reflection.

This video explores diffraction as waves spread through gaps, focusing on the interference pattern created in single-slit setups and how it is influenced by wavelength and slit width.

This video introduces the double-slit experiment, detailing the interference pattern formed and explaining how to calculate fringe separation and slit spacing using standard formulas.

This video explores single-slit diffraction, explaining amplitude and intensity patterns and how they are influenced by factors like slit width, light wavelength, and source intensity.

This video introduces calculations for double-slit diffraction and explains how diffraction gratings improve pattern clarity. It also defines resolvance and how it relates to slit number and diffraction order.

This video explains thin film interference, focusing on how reflected rays from different surfaces interfere depending on path difference and phase change. It includes equations for determining constructive and destructive interference.

This video introduces standing waves, comparing them to travelling waves, and explains how harmonics form with nodes and antinodes depending on wave constraints.

This video explores how different boundary types—fixed, open, or mixed—affect standing wave patterns and the harmonic series, with examples like strings and pipes.

This video explains how damping reduces amplitude over time and explores how it affects the energy and frequency of oscillating systems, including light, critical, and heavy damping.

This video explores the concept of driving frequency, how it leads to resonance when matched to natural frequency, and the practical benefits and risks of resonance in real systems.

This video explains the Doppler effect for sound and light waves, detailing how motion between the source and observer alters perceived frequency. It also introduces formulae for calculating the speed of distant objects based on light wavelength changes.

This video explores real-world uses of the Doppler effect, including radar speed detection, ultrasound blood flow measurement, and galactic motion through redshift and blueshift in absorption spectra.

This video presents formulae to calculate observed frequency for moving sources and observers. It distinguishes between motion toward and away from the other object, allowing full Doppler effect calculations with sound waves.
