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 Reflection is the abrupt change in the direction of propagation of a wave that strikes the boundary between two different media. At least some part of the incoming wave remains in the same medium. Assume the incoming light ray makes an angle Î¸i with the normal of a plane tangent to the boundary. and T depend on the indices of refraction of the two media n1 and n2, the angle of incidence Î¸1, and the polarization of the incident light. We distinguish between p-polarization and s-polarization. Let the plane of incidence contain the normal to the boundary and the incident wave vector k1.
