Lambda is a Greek letter (uppercase Λ, lowercase λ) used in physics (particularly optics, electromagnetism and Spectroscopy). It is a figure used for wave length.
It can be used as a side length, which has many possibilities to figure with.
Often, but not always.
Base and height
The metre.
The maximum length is 6, because 2 are used to give the figure height. Hope this helps!! :)
The meter is used to measure length.
it measure the length of time and space of a figure
Mass: kilogram Length: meter Volume: cubic meter (this is not a base unit, since it is derived from the meter)
The length of the head, from chin to top of skull, is the unit usually used to define the proportions of an individual figure.
area is usually defined with a big A.
If you used millimeters, the figure would be too large. If you used kilometers, the figure would be too small. Meters are just right.
