Question

An object is placed at a distance of 20cm from a convex mirror of focal length 15cm. Find the position and nature of the image

Answer 1

beyond 2f on other side of lens

Real, innverted,karege

Answer 2

$\bf\huge u = -20cm , f = 15cm$

$\bf\huge\frac{1}{f} = \frac{1}{u}+\frac{1}{v}$

$\bf\huge\frac{1}{v} = \frac{1}{15} - \frac{1}{-20}$

$\bf\huge\frac{1}{v} = \frac{1}{15} - \frac{1}{20}$

$\bf\huge\frac{1}{v} = \frac{7}{60}$

$\bf\huge\texttt v = 8.57 cm$

$\bf\huge\boxed{\boxed{\:Nature\:of\:Image\:=\:Virtual}}}$
