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).
The law of reflection states that the angle of incidence is equal to the angle of reflection, and this law is observed on both smooth surfaces producing specular reflections (where reflected rays are all bounced off at the same angle) and diffuse reflections (incident rays bouncing off at multiple reflected rays).
