Answer 2

Answer:

the image formed is real inverted and diminished in nature and it is formed in between the focus and centre of curvature .

Explanation:

here. v=15cm

f=10cm

according to Mirror formula ,1/v+1/u=1/f putting these value we get,

1/15+1/u=1/10

• 1/u=1/10-1/15
• =3-2/30

=1/3o

u=30

magnification (m) =v/u

=15/30

=1/2

so, m=v/u=1/2.<1

• so the image is real inverted and diminished .
• and it is situated in between focus and centre of curvature
