👉 In physics, an attenuator is a device that decreases the intensity of light or other electromagnetic waves. It works by absorbing or filtering out some of the wave's energy, making it less effective at transmitting information. The term "attenuator" refers to the process of reducing the intensity of light or other electromagnetic waves through the use of a device such as an attenuator. This can be used for various purposes, including improving signal transmission in telecommunications networks, enhancing the effectiveness of microphones and loud
