Character	Name	Code point	HTML	LaTeX
	U+03BB. Eleventh in the Greek alphabet, the letter for the sound l. Science writes wavelength with it. Unicode spells its name lamda, as modern Greek does. No Alt code types it; HTML has λ and LaTeX \lambda.
	U+039B. Capital lambda, two strokes that meet at the top. Cosmology writes the cosmological constant with it. HTML has Λ and LaTeX \Lambda; no Alt code types it.
	U+1D706. Small lambda as the italic letter of the math alphabets, for a wavelength or an eigenvalue in a formula.
	U+1D6EC. Uppercase lambda, italic, from the math alphabets; its decomposition is U+039B.
	U+019B. Barred lambda, or lambda bar: a Latin letter of Americanist phonetic writing. It sits in the Latin Extended-B block, away from the Greek letter.

How it works

λ is the lambda symbol: Greek small letter lamda in Unicode's spelling, U+03BB, the eleventh letter of the Greek alphabet. The rows add the capital Λ, math styles such as 𝜆, the barred ƛ, and the look-alikes ∧ and Ʌ.

Read the full guide

Lambda is the Greek letter for l

Lambda writes the sound l, and the Latin L and the Cyrillic Л both came from it. Unicode names the two characters lamda, with no b, the way modern Greek spells the word.

Λ, ∧ and Ʌ are three characters

Λ, U+039B, is capital lambda. ∧, U+2227, is the logical and sign, &and; in HTML and \wedge in LaTeX. Ʌ, U+0245, is a Latin V turned over, a letter with no tie to lambda.

As a Greek numeral lambda is 30, written λʹ.
ƛ, the barred lambda, is a Latin letter of Americanist phonetic writing.

Questions and answers

What is the Alt code for the lambda symbol?

Not among the standard ones. The character set behind the three-digit Alt codes has a dozen Greek letters, α, δ and π among them, and neither λ nor Λ. Codes above 255 depend on the program, so copying is the short way.

How do I write lambda in HTML and LaTeX?

In HTML λ is the small letter and Λ the capital, λ and Λ as numbers. LaTeX prints them with \lambda and \Lambda in math mode.

Which Greek letter stands for wavelength?

Small lambda, λ. Physics writes the wavelength of a wave with it: the distance over which the shape of the wave repeats.

What else does the lambda letter stand for?

Small λ marks an eigenvalue in linear algebra, a decay constant in nuclear physics and an anonymous function in computing, as in λx.x. Capital Λ is the cosmological constant of the ΛCDM model.

How do you say lambda?

English says LAM-da and leaves the b silent. Modern Greek spells the name without the b.
