Write the relationship between the radius of curvature and the focal length for a spherical mirror.
(N/A) For a spherical mirror of small aperture,the relationship between the radius of curvature $(R)$ and the focal length $(f)$ is given by the formula:
$R = 2f$
Alternatively,it can be expressed as:
$f = \frac{R}{2}$
This indicates that the focal length is half of the radius of curvature.
$R = 2f$

Assertion : $A$ point object is placed at a distance of $26 \ cm$ from a convex mirror of focal length $26 \ cm$. The image will not form at infinity.
Reason : For the above-given system,the equation $\frac{1}{v} + \frac{1}{u} = \frac{1}{f}$ gives $v = \infty$.
