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 mirror might look silver because it's usually depicted that way in books or movies. However, it's actually the color of whatever is reflected onto it. A perfect mirror has specular reflection, meaning it reflects all light in a single direction equal to what it receives. Specular reflection creates an image of whatever object is in front of it. But most mirrors we use aren't perfect.
