Wave Behavior and Light Phenomena

The video explores how light and sound waves behave, focusing on key behaviors such as reflection, transmission, absorption, refraction, diffraction, and scattering. Reflection involves waves bouncing off surfaces, while transmission sees them continue through a medium. Absorption and reflection determine an object's color based on which wavelengths are absorbed or reflected. Refraction occurs when waves change speed and direction at a boundary, causing visual distortions. Diffraction involves waves spreading out after passing through a gap, and scattering explains phenomena like the blue sky. Each behavior is influenced by the material the waves encounter.

What are the two main types of waves discussed in the video?

• Sound and Light

• Primary and Secondary

• Electromagnetic and Mechanical

• Transverse and Longitudinal

Why do we hear echoes when sound waves hit hard surfaces?

• Because sound waves are refracted

• Because sound waves are reflected

• Because sound waves are transmitted

• Because sound waves are absorbed

What happens to light when it passes through a window?
