The Doppler Effect: Why Sounds Change as They Move

This Doppler effect lesson breaks down how sound and light waves shift based on movement. It explores pitch, frequency change, redshift, and real-world uses in radar, medicine, and astronomy. Learn how waves behave with motion using step-by-step explanations and visual thought experiments.

The Nature of Light: Waves and Particles

Light doesn’t act like just a wave or a particle—it shows properties of both. This wave particle duality is a core idea in modern physics. From double-slit experiments to photon behaviour in solar panels, understanding light helps explain everything from rainbows to quantum theory.
