See your GP if you have: 1  persistent or worrying symptoms that could be caused by haemochromatosis â particularly if you have a northern European family background. 2  a parent or sibling with haemochromatosis, even if you don't have symptoms yourself â tests can be done to check if you're at risk of developing problems.
The reflection of light can be roughly categorized into two types of reflection: specular reflection is defined as light reflected from a smooth surface at a definite angle, and diffuse reflection, which is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 1).
Regular Reflection. If a parallel beam of light is reflected as a parallel beam, when it strikes on a smooth and polished surface, then it is called regular reflection. Plane Mirror: Looking glass, polished metal surfaces, mercury surface and smooth surface of water are all called plane mirrors. Irregular Reflection: If a parallel beam of light is reflected as in different directions, when it strikes on a rough surface, then it is called irregular reflection.
