Explanation:
1f=1v-1u+>1v=1f+1u⇒v=u×fu+f;f=
(i)
v=(-30)×2020-30=60
cm
The image is formed at a distance of 60 cm on the other side of the optical centre
(ii)
m=-vu=-60-30=2
(iii) Image formed is inverted.
An Object is Placed Perpendicular to the Principal Axis of a Convex Lens of Focal Length 20 Cm. the Distance of the Object from the Lens is 30 Cm. Find (I) the Position (Ii) the Magnification and Concept: Refraction of Light - Image Formation by Lenses - Convex Lens.
