Definition

Meaning and Definition

The degree to which a material allows electromagnetic radiation (such as light) to pass through it; the property of being transmissive.

In a broader technical context, the measure of how effectively energy or signals are transmitted through a medium, with applications in optics, acoustics, and telecommunications.

Common Mistakes When Using “transmittivity”

  • Using it as a synonym for 'transmission' (the process).
  • Confusing it with 'conductivity' (for electricity or heat).
  • Mispronouncing as /trænzˈmɪtɪvɪti/ (stress on 'mit'). Correct stress is on 'tiv'.
  • Misspelling as 'transmitivity' (missing one 't').

FAQ

Frequently Asked Questions

No. Transparency is a qualitative, everyday term meaning 'see-through'. Transmittivity is a quantitative, scientific measurement of how much radiation passes through.

In many technical contexts, especially in optics, 'transmittance' is a direct synonym and is often preferred.

Primarily for electromagnetic radiation (light, radio waves). For sound, the related term is 'acoustic transmittance' or 'sound transmission loss'.

No. It is a highly specialized term you will only encounter in technical literature related to materials science, photonics, or telecommunications.

The degree to which a material allows electromagnetic radiation (such as light) to pass through it.

Transmittivity is usually highly technical/scientific in register.

Transmittivity: in British English it is pronounced /ˌtrænzmɪˈtɪvɪti/, and in American English it is pronounced /ˌtrænzmɪˈtɪvɪti/. Tap the audio buttons above to hear it.

Learning

Memory Aids

Mnemonic

Think: 'TRANS' (across) + 'MIT' (send) + 'TIVITY' (the quality of). It's the 'quality of sending through' light or signals.

Conceptual Metaphor

The material acts as a gatekeeper or window for radiation; transmittivity is the gate's openness.
