How Refraction Makes This Beaker Disappear Refraction is the change in direction of a wave, typically light, as it passes from one medium to another with a different optical density, due to a change in wave speed. When light travels from a less optically dense medium (like air) into a more optically dense one (like glass or water), it slows down and bends toward the normal (a line perpendicular to the boundary surface). This phenomenon is governed by Snell’s Law, expressed as n₁sinθ₁ = n₂sinθ₂,

Refraction of Light What is Refraction of Light Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light Join The Cavalier Academy for complete and thorough preparation of all Defense Exams & SSB Interview. To Register for 𝑶𝒇𝒇𝒍𝒊𝒏𝒆 𝑪𝒍𝒂𝒔𝒔𝒓𝒐𝒐�
