Cách sử dụng
A reflector is a object that sends or reflects light or sound back in the direction it came from. You might often see reflectors on the back of a bicycle or a road sign, as they help increase visibility and safety. They can also be used in photography to reflect light onto a subject, or in telescopes to direct light to the eyepiece.
