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).
2) A ray that is incident and passes through the focal point of the mirror is rendered. parallel to the optic axis after reflection and is called the focal ray. 3) A ray that is incident and passes through the center of curvature C is reflected. back through C and is called the chief ray.
