Manipulating Light

The video tutorial explores how light interacts with different surfaces and materials. It covers the concepts of reflection, where light bounces off surfaces, and refraction, where light changes direction when passing through different media. The tutorial also explains diffraction, which occurs when light bends around obstacles, and how shadows form and blur. Additionally, it discusses wave interaction, where light waves combine to create patterns, and absorption, where light is converted into other energy forms. The importance of light energy for life on Earth is also highlighted.
