Focal Length of Concave Mirror Calculator

Calculate Focal Length of Concave Mirror



Formula

The formula to calculate the Focal Length of Concave Mirror is:

\[ f_{\text{concave}} = \frac{r_{\text{concave}}}{2} \]

Where:

Definition

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.

Example Calculation

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.
