Question

What is the dimensional formula of light year?

Answer 1

as light year is a measure of distance
the dimension will be = M0 L1 T0

Answer 2

[L] is the dimension of light year.

Explanation:

The dimensional formula is calculated over the known 7 fundamental units already given a fundamental dimensional value.

Thereby, the light year is the standard unit of measurement of measuring the distances between celestial bodies or rather say the astronomical distances.

The distances are written in dimensional formula as L

The dimensional formula for light year thus is given below:

$\text { Light year } =\left[M^{0} L^{1} T^{0}\right]$

$\Rightarrow \text { Light year } = [L]$
