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 is a characteristic of any waves at the boundary. There is refraction, too. Transmission line is only a medium for waves traveling in 1-D. Reflection occurs when the transmission line is not matched at the end. Short and open ciruits are two special cases. It could be better understood if you think of the em wave rather than circuit.
