Question

Q33. An object of height 5 cm is held 30 cm away from a converging lens of focal length
10 cm. Find the position, size and nature of the image formed. 3​

Answer 1

Answer:

Given, u=-20cm

f=10cm

v=?

We know

f1=v1−u1

101=v1−20(−1)

v1=202−1

v=20cm

We know

magnification (M)=hohi=u−v

or,−2020=−1=hohi since,h0=5cm

so,hi=−5cm

nature = real image
