## Background

Another fundamental physical constant named after Max Planck, it is thought to be the smallest possible length, at an incredibly small 1.616 x 10^{-35} meters.

## Energy Wave Constants – Equivalent

The following is the representation of this fundamental physical constant expressed in energy wave theory. Using energy wave constants, its value was calculated and shown to match the known value in the Summary of Calculations table.

### Planck Length

Planck length was derived from a known relation of the square of the reduced Planck constant to the gravitational constant (G) and the cube of the speed of light. Although Planck length was derived correctly in value and units, the meaning based on the equation below is unclear – see relationship to fine structure constant below.

**Calculated Value: **1.6162E-35

**Difference from CODATA:** 0.000%

**Calculated Units**: m

The complete derivation of this constant is available in the Fundamental Physical Constants paper.

## Alternative Derivation

An alternative version after substituting for δ_{Ge }and O_{e}.

## Relationship to the Fine Structure Constant

Some of the derivations of the wave energy equations appear to be complex, yet their calculations match the known CODATA value. This is one of the energy wave constants that has a connection to the fine structure constant that simplifies the equation and provides some meaning to the constant itself.
