Using GA Standards s8P4a. Wavelength, frequency, wave reflection and refraction as well as diffraction and types of interference.

The Anatomy of a Wave (00:00 - 01:20)

• Exploration of basic wave properties including wavelength and frequency.

• Discussion on the inverse relationship between how long a wave is and how often it repeats.

Refraction and Reflection (01:20 - 02:45)

• Explanation of reflection as waves bouncing off surfaces, using mirrors and echoes as primary examples.

• Detailed look at refraction, specifically how waves bend when changing speeds across different mediums, such as light traveling through air into water.

Diffraction and Obstacles (02:45 - 03:50)

• Analysis of how waves behave when encountering gaps or corners.

• Discussion on why sound can be heard around obstacles even when light is blocked.

Interference Patterns (03:50 - 05:00)

• Comparison between constructive interference, which increases wave amplitude, and destructive interference, which reduces it.

• Real-world application of wave interference in technology like noise-canceling headphones.
