Light Behavior and Sound Waves

The video tutorial discusses the behavior of light and sound waves, focusing on three key phenomena: reflection, refraction, and diffraction. Reflection is explained with examples like mirrors and echoes. Refraction is illustrated through water, prisms, and eyeglasses, showing how light bends. Diffraction is described as the bending of waves around obstacles, with examples like sound traveling around corners. The video aims to clarify these concepts with visual and practical examples.

• They diffuse light

Why can you hear someone around a corner but not see them?

• Light waves are absorbed

• Light waves are refracted

• Sound waves diffract better than light
