The formula to calculate the Focal Length of Convex Mirror is:
\[ f_{\text{convex}} = \frac{1}{\left(\frac{1}{u_{\text{convex}}}\right) + \left(\frac{1}{v_{\text{convex}}}\right)} \]
Where:
Focal Length of Convex Mirror is the distance between the mirror's vertex and the focal point, which is the point where parallel rays of light converge after being reflected by the mirror.
Let's assume the following values:
Using the formula:
\[ f_{\text{convex}} = \frac{1}{\left(\frac{1}{0.4667}\right) + \left(\frac{1}{-0.4}\right)} \]
Evaluating:
\[ f_{\text{convex}} = -2.79880059970015 \text{ m} \]
The Focal Length of Convex Mirror is -2.79880059970015 m.
