if you are talking about physics, then it is wavelength of the light
The Lambda, I assume, is used as a pride symbol for many things. However, the first thing that comes to mind (and these thoughts are supported by the categories it has been placed into), is the symbol of the GLBTQ community. The Lambda itself stands for Liberation, and more information of it can be found here: http://en.wikipedia.org/wiki/LGBT_symbols#Lambda
answer: λ
Lambda
As far as I know, it is not. No, their main symbol is the lambda
Lambda is usually specified to mean wavelength in mathematics and physics.
lambda is the symbol of the ancient Greek's. (not the Greeks 500bc but hundreds of years before 500bc. lambda symbol used also when they were building gates. the lambda symbolises the (biological) source of the Greek's witch is from the Nephelims called "the twelve gods". lambda also presents the gene that is different in Greek's than other group of people..
The symbol for wavelength is the Greek letter lambda (λ). It is used to represent the distance between two consecutive points on a wave where the waveform repeats itself.
Lambda sensors. The 3 leg symbol (upside down 'Y') is the greek lambda symbol
In physics, lambda (λ) represents the wavelength of a wave, such as light or sound. It is the distance between consecutive points on a wave that are in phase with each other. Lambda is a key parameter in understanding wave behavior and properties.
The symbol for representing the period of a wave is the greek letter lambda (λ).
In the ancient Greek system, the letter Lambda had a value of 30. Nowadays, the lower case lambda stands for the wave length. In statistics, it is the parameter of the Poisson distribution and represents the reciprocal of the frequency.
