The image above represents linear density. To calculate linear density, two essential parameters are needed, and these parameters are **Number of Atoms Centered on Direction Vector (N)Â **andÂ **Length of Direction Vector (L).**

**The formula for calculating linear density:**

LD =Â ^{N}/_{L}

Where:

LD = Linear Density

N = Number of Atoms Centered on Direction Vector

L = Length of Direction Vector

Given an example;

Find the linear density when the number of atoms centered on direction vector is 10 and the length of direction vector is 2.

This implies that;

N = Number of Atoms Centered on Direction Vector = 10

L = Length of Direction Vector = 2

LD =Â ^{N}/_{L}

That is, LD = ^{10}/_{2}

LD = 5

Therefore, theÂ **linear densityÂ **isÂ **5 atoms/m.**

**Calculating the Number of Atoms Centered on Direction Vector when the Linear Density and the Length of Direction Vector are Given**

N = LD x L

Where:

N = Number of Atoms Centered on Direction Vector

LD = Linear Density

L = Length of Direction Vector

Let’s solve an example;

Find the number of atoms centered on direction vector when the linear density is 6 and the length of direction vector is 5.

This implies that;

LD = Linear Density = 6

L = Length of Direction Vector = 5

N = LD x L

So, N = 6 x 5

N = 30

Therefore, theÂ **number of atoms centered on direction vector **isÂ **30 atoms.**

**Calculating the Length of Direction Vector when the Linear Density and the Number of Atoms Centered on Direction Vector are Given**

L = ^{N} / _{LD}

Where:

L = Length of Direction Vector

LD = Linear Density

N = Number of Atoms Centered on Direction Vector

Let’s solve an example;

Find the length of direction vector when the linear density is 12 and the number of atoms centered on direction vector is 72.

This implies that;

LD = Linear Density = 12

N = Number of Atoms Centered on Direction Vector = 72

L = ^{N} / _{LD}

So, L = ^{72} / _{12}

L = 6

Therefore, theÂ **length of direction vectorÂ **isÂ **6 m.**
