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).
A reflection is called a rigid transformation or isometry because the image is the same size and shape as the pre-image. The reflection line, m, is the perpendicular bisector o f the segments joining each point to its image. Notice that these segments are parallel, since they are perpendicular to the same line.
