Optical effects

Optical effects are phenomena involving the interaction of light with materials or surfaces, creating visual changes we can observe. Examples include reflection, where light bounces off surfaces; refraction, where light bends passing through different mediums like glass or water; diffraction, where light spreads out after passing through narrow openings; and interference, where overlapping light waves can amplify or cancel each other. These effects explain how we see colors, illusions, rainbows, or holograms, and are fundamental to how optical devices like lenses, telescopes, and projectors work.
