I WONDER - What Is Reflection And Refraction?

The video tutorial explores how waves interact with their environment through reflection, refraction, and diffraction. Reflection is when waves bounce back from a surface, causing echoes. Refraction occurs when waves change direction as they pass through different media, like a straw appearing bent in water. Diffraction involves waves bending around obstacles or spreading through narrow openings, allowing sound to be heard even when the source is obscured.

What are the different ways waves can interact with their environment?

How does the interaction of waves with obstacles lead to the ability to hear sounds from behind a wall?
