SpletRefraction is a physical property of light where its speed and wavelength are altered as it passes from one medium to another. A medium is what the light has to pass through, this can be either a solid, liquid, or gas object. It can even represent a vacuum. diy 2x4 floating shelvesSpletThe angles of incidence, reflection and refraction are θ i, θ r and θ t.
