Nontransmittance refers to the inability of something, such as light, sound, or energy, to pass through or be transmitted from one medium to another. It is the quality or state of not being transmitted. Nontransmittance can occur due to various factors including physical barriers, absorption, or reflection.
In the context of light, nontransmittance signifies the obstruction or prevention of light waves from passing through a material or substance. This can be caused by the material's opaque nature, which does not allow any light to pass through, or by its incapability to transmit certain wavelengths of light. For example, in the case of an opaquely painted glass, nontransmittance would occur because the pigment in the paint blocks the passage of light.
Similarly, nontransmittance can apply to sound waves when they are unable to pass through a medium due to obstructions or properties of the material that impede the transfer of sound. For instance, when sound waves encounter a thick wall, their nontransmittance refers to their failure to penetrate the wall and reach the other side.
Nontransmittance can also describe the lack of transmission of energy, such as heat or electrical current, from one medium to another. In this case, it often refers to materials or structures that are good insulators, preventing the transfer of energy and maintaining the separation of different mediums.
Overall, nontransmittance is the quality or state of not being transmitted, representing the inability of light, sound, or energy to pass through or reach another medium.
