The formula to calculate the Focal Length of Concave Mirror with Real Image is:
\[ f_{\text{concave, real}} = \frac{v_{\text{concave, real}} \cdot u_{\text{concave, real}}}{v_{\text{concave, real}} + u_{\text{concave, real}}} \]
Where:
The Focal Length of Concave Mirror with Real Image is the distance between the mirror's vertex and the image formed by the mirror when the object is real, and the image is real.
Let's assume the following values:
Using the formula:
\[ f_{\text{concave, real}} = \frac{v_{\text{concave, real}} \cdot u_{\text{concave, real}}}{v_{\text{concave, real}} + u_{\text{concave, real}}} \]
Evaluating:
\[ f_{\text{concave, real}} = \frac{0.1 \cdot 0.06}{0.1 + 0.06} \]
The Focal Length is 0.0375 meters.
