Given:
The size of object = 4.0cm
Distance of the object = 25cm (-ve as it is in front
of mirrors)
focal length of concave mirror = 15cm (-ve) Distance of the image is given by
1/v+1/u = 1/f
1/v +1/-25=1/-15
1/v = 1/-15+1/25
= -10+6/150
=-4/150=v
<h2>v = -37.5</h2>
The size of the image is given by
h^1/h^0 =-v-/u
h^1 = -v- *h^0
=> -(-37.5)*4/25
=>-150/25
=> -6 Cm
<h2>Image will be 6cm high and it will be inverted.</h2>
( Negative sign indicates that the image is below
the principal axis.
Therefore, the size of the image is 6 cm.)
