Physics of waves: Covers Quantum Waves, sound waves, and light waves. Easy to understand explanation of refraction, reflection, and many other topics. Important correction: In the section of refraction, the colors are reversed. Violet light slows down in water more than red light, and violet light therefore bends more than red light when it transitions from air to water.
