QUESTION:

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

nature of the image.

Given:

Focal length(f) = 20 cm

Distance of object from convex mirror= 15 cm

Formula:

$\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$

SOLUTION:

$\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$

$\frac{1}{v} = \frac{1}{20} + \frac{1}{15}$

$\frac{1}{v} = \frac{3 + 4}{60}$

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

$v = \frac{60}{7} \: cm$

Answer:

QUESTION:

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

nature of the image.

Given:

Focal length(f) = 20 cm

Distance of object from convex mirror= 15 cm

Formula:

$[tex] \frac{1}{v} - \frac{1}{u} = \frac{1}{f}$[/tex]

SOLUTION:

$\frac{1}{v} - \frac{1}{u} = \frac{1}{f}$

$\frac{1}{v} = \frac{1}{20} + \frac{1}{15}</p><p>\frac{1}{v} = \frac{3 + 4}{60}</p><p>\frac{1}{v} = \frac{7}{60} \\ v = \frac{60}{7} \: cm$
