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 the rebounding of light from the surface of an object. Refraction is the passing of light through a medium (may be liquid or a transparent solid) with some change in the velocity of light during the process.eflection: When light beam is in contact with a reflective polished surface than it traces its path according to laws of reflection. Diffraction: Its a phenomenon by which light bends around the corner of small obstacles and it spreads out. (You can imagine this obstacle as a very sharp corner of a lab plane mirror).
