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).
Reflection of light and other forms of electromagnetic radiation occurs when waves encounter a boundary that does not absorb the radiation's energy, but instead bounces the waves off its surface. In such cases, the incoming light wave is referred to as an incident wave and the wave that is bounced from the surface is called the reflected wave.
