You wish to determine the focal length $f$ of a concave spherical mirror. In order to do this, you determine the image distance $q$ for several different values of the object distance $p$ . How could you use these data to determine $f$ ?

Options:

Answer:

Solution:

Mirror formula is $\frac{1}{p} + \frac{1}{q} = \frac{1}{f}$ ; compare with $y = m x + c$ , so $\frac{1}{f}$ is the y-intercept.
