In this episode Mark Reggers is joined by guest Kosta Karagiannopoulos, 3M's Application Engineering Specialist for the Transportation Safety Division in Australia and New Zealand to discuss the science of retro reflectivity. Retro reflectivity or retro reflection occurs when a surface returns a large portion of a directed light beam back to its source. It helps the eye perceive objects in low light conditions when illuminated by a light source. The science of retro reflectivity is incorporated into safety garments, traffic control devices, vehicle markings and many more applications to keep people safe when it is dark and visibility is reduced.
