Learn about and revise reflection, including specular and diffuse reflections, and refraction of light waves with GCSE Bitesize Physics.

Diffuse reflection If a surface is rough, diffuse reflection happens. Instead of forming an image, the reflected light is scattered in all directions.

Reflections that add coherently at lower frequencies become incoherent at higher frequencies, reducing fringe contrast but not affecting the phase measurement. Measuring Specular Features and Surfaces ...

Smooth surfaces, as polished, coated, or wet surfaces, produce specular reflections under unfavourable lighting conditions. Image processing algorithms, such as any correlation-based computation, may ...
