Light reflects from a smooth surface at the same angle as it hits the surface. For a smooth surface, reflected light rays travel in the same direction. This is called specular reflection. For a rough surface, reflected light rays scatter in all directions. This is called diffuse reflection.
Reflection. When light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it. Smooth, shiny surfaces such as mirrors and...
Learn about and revise reflection, including specular and diffuse reflections, and refraction of light waves with GCSE Bitesize Physics.
When light from an object is reflected by a surface, it changes direction. It bounces off the surface at the same angle as it hits it. Showing how rays from the Sun are reflected at the same...
Key learning points. Specular reflection is reflection from a smooth surface in a single direction. Diffuse reflection is reflection from a rough surface in multiple directions. The angle of incidence equals the angle of reflection. Angles are measured from the normal.
We can now see how to answer the following question: If a light wave in glass arrives at the surface at a large enough angle, it is reflected; if another piece of glass is brought up to the surface (so that the “surface” in effect disappears) the light is transmitted.
Oct 21, 2024 · Light - Reflection, Refraction, Physics: Light rays change direction when they reflect off a surface, move from one transparent medium into another, or travel through a medium whose composition is continuously changing. The law of reflection states that, on reflection from a smooth surface, the angle of the reflected ray is equal to the angle ...
