Focal Length of Concave Mirror with Real Image Calculator

Calculate Focal Length of Concave Mirror with Real Image





Formula

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:

Definition

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.

Example Calculation

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.
