*[[Attenuation]], a reduction in amplitude and intensity of a signal
*In telecommunications, loss is a decrease in signal in a communications system:
**[[Angular misalignment loss]], power loss caused by the deviation from optimum angular alignment
**[[Bridging loss]], the loss that results when an impedance is connected across a transmission line
**[[Coupling loss]], the loss that occurs when energy is transferred from one circuit, optical device, or medium to another
**[[Insertion loss]], the decrease in transmitted signal power resulting from the insertion of a device in a transmission line or optical fiber
**[[Path loss]], the attenuation undergone by an electromagnetic wave in transit from a transmitter to a receiver
***[[Free-space path loss]], the loss in signal strength that would result if all influences were sufficiently removed having no effect on its propagation
**[[Reflection loss]], a loss which causes energy to be reflected back toward its source
**[[Return loss]], the ratio of the amplitude of the reflected wave to the amplitude of the incident wave
* in [[laser physics]], loss (or background loss, or [[round-trip loss]]) may refer to the part of the energy of the optical field, that becomes unusable at each rond-trip in the cavity due to the scattering or absorption.
