How does a current mirror work
WebApr 10, 2024 · When light sensors on the mirror catch glare, a current is sent to the electrochromic gel that sits between two pieces of glass in the mirror. This current causes the gel to change color, which dims the appearance of the mirror. When there is no more glare to trigger the sensor, the current stops. WebAug 5, 2009 · Mirror Physics. In order to understand mirrors, we first must understand light. The law of reflection says that when a ray of light hits a surface, it bounces in a certain way, like a tennis ball thrown against a …
