1. The 11th letter of the Greek alphabet, represented in the English alphabet as "L".
2. The point of junction at the center of the back of the cranium (skull) between the rear plate of the cranium occipital bone and the two upper plates parietal bones.

This junction is said to resemble the Greek capital letter lambda.
3. The craniometric point at the junction of the sagittal and lamboid sutures of the skull.
4. The point at the site of the posterior fontanel where the lambdoid and sagittal sutures meet; used as a craniometric landmark.

An individual wavelength of light for transmitting data on a strand of fiber-optic cable.

Using separate lasers, each tuned to a slightly different frequency, multiple lambdas can be projected down a single fiber strand to carry multiple streams of data.

DWDM (dense wavelength division multiplexing) is the technology for projecting multiple lambda circuits on fiber strands. Currently, 200 lambdas per fiber is common, but thousands are possible.

1. A speech disorder consisting of the substitution of "L" for "R".
2. A speech disorder involving the faulty pronunciation of "L".

Shaped like the Greek letter Λ or λ.
