World Bytes .io on Instagram: "The post features a compilation video of creative low-tech photography hacks, such as using fishing rods for overhead shots and foam for illusory ice tunnels, transforming everyday items into tools for dramatic effects like perfect reflections and forced perspectives. These techniques leverage basic optics principles, including refraction in water and light scattering on powders, enabling stunning results without specialist equipment, which echoes @sciencegirl 's b

Explainiosity on Instagram: "The post demonstrates how a beam of light changes direction when passing through different glass shapes due to refraction, revealing how optics work at a fundamental level. As light moves from air into glass, its speed changes, forcing it to bend, and the direction of that bend depends entirely on the shape and geometry of the glass. Parallel red light rays passing through a convex lens curve inward and converge at a focal point, explaining why such lenses are used i
