Question

in an experiment to determine the focal length of a concave mirror, the mirror of 5 cm, focal length is placed at 10 cm mark of metre scale. the position of the screen on metre scale is​

Answer 1

Object Distance(u) = 10 cm. (negative)

Focal length of the lens (f) = 5 cm.

We know, convex mirror always forms the virtual, upright and diminished.Also, Object distance in the convex mirror is always negative where as Image distance and focal length are positive.

Now, Applying the Mirror's Formula,

f/f=1/v+1/u

=1/5=1/v+1/u

= 10v(10−v)

10v=50−5v

15v=50

v=10/3

v=3.33
