Wave Interactions: Reflection, Refraction, and Diffraction
Discover how waves bounce, bend, and spread as they interact with surfaces, media, and obstacles and explore the real-world technologies these behaviors make possible.
What You'll Learn
Reflection follows the law: angle of incidence equals angle of reflection.
Refraction bends waves when speed changes between different media.
Diffraction spreads waves most when openings match the wavelength size.
Total internal reflection traps light inside fiber optic cable cores.
What You'll Practice
1
Students identify reflection, refraction, and diffraction in real scenarios.
2
Learners apply the law of reflection and index of refraction concepts.
3
Practice questions test diffraction conditions and total internal reflection.
Why This Matters
Understanding wave interactions reflection, refraction, and diffraction is essential for explaining natural phenomena and the technologies that define modern communication, medicine, and engineering.
