MAGNITUDE AND DIRECTION OF A VECTOR
Given a position vector →v=⟨a,b⟩,the magnitude is located by |v|=√a2+b2. The direction is equal to the angle formed with the x-axis, or with the y-axis, depending on the application. For a position vector, the direction is found by tanθ=(ba)⇒θ=tan−1(ba)
<h3>What is the formula of magnitude?</h3>
The formula to determine the extent of a vector (in two dimensional space) v = (x, y) is: |v| =√(x2 + y2). This formula is derived from the Pythagorean theorem. the procedure to determine the magnitude of a vector (in three dimensional space) V = (x, y, z) is: |V| = √(x2 + y2 + z2)

We need to calculate the enthalpy change first:
Keep in mind this is the energy per mole, we need energy per atom:
We can see that this reaction needs the energy to get started (enthalpy change is positive).
The energy of a photon is given with this formula:
We need this photon to have the same energy (or higher) as our enthalpy change:
This wavelenght is clasified as near infrared.
