The formula to calculate the Focal Length of Concave Mirror is:
\[ f_{\text{concave}} = \frac{r_{\text{concave}}}{2} \]
Where:
The Focal Length of Concave Mirror is the distance between the mirror's vertex and the focal point, where parallel rays of light converge after reflection from the concave mirror.
Let's assume the following value:
Using the formula:
\[ f_{\text{concave}} = \frac{0.5}{2} \]
Evaluating:
\[ f_{\text{concave}} = 0.25 \text{ m} \]
The Focal Length of Concave Mirror is 0.25 m.
