Transmission vs. Transmittance: Know the Difference
By Shumaila Saeed || Updated on December 29, 2023
Transmission refers to the process of sending something (energy, information) from one place to another, while transmittance measures the fraction of light that passes through a substance.
Key Differences
Transmission is the process or act of transferring something from one place, person, or thing to another. It is commonly used in the context of conveying information, energy, or physical objects. In physics, it refers to the passage of waves or particles through a medium. Transmittance, on the other hand, is a specific term in optics and materials science. It quantifies the amount of light or radiation that passes through a material. Transmittance is expressed as a ratio or percentage, indicating how much of the incident light is transmitted through the substance.

In telecommunications, transmission involves sending information, like data or voice, over distances using electronic or electromagnetic signals. This encompasses a wide range of technologies and methods, from radio broadcasts to internet data packets. Transmittance in this context is not a directly related concept. However, in the design of optical fibers used for data transmission, the transmittance of the fiber material becomes crucial as it affects the efficiency and quality of data transmission.

In mechanical systems, transmission refers to the mechanism that transmits mechanical power from an engine or motor to the point of application, like in a car's gearbox. It involves the physical transfer of energy. Transmittance has no direct relevance in this context. It remains a term primarily used in optics, measuring how materials like glass or plastic transmit light.

Transmission in biology and medicine refers to the spread of disease or genetic information from one organism to another. It's a key concept in understanding the dynamics of infectious diseases and genetics. Transmittance is not a term generally used in biological contexts. In medicine, it could refer to the passage of light through tissues, important in certain diagnostic imaging techniques.

Transmission can also refer to the conveying of cultural or intellectual property, like traditions or knowledge, from one generation to another. It's about the movement and sharing of intangible assets. Transmittance in such abstract contexts is not applicable, as it strictly pertains to the physical passage of light or radiation through materials.
