Question

A 6 centimetre tall object in front of converging lens of focal length 15 centimetre object distance 10 cm and find position size and nature of image​

Answer 1

Answer:

image distance : -30cm

size : 18cm

nature of image : Virtual

Explanation:

h = 6cm

f = 15cm (focal length is positive as it is convex)

u = -10cm

_______

1/v - 1/u = 1/f

1/v + 1/10 = 1/15

1/v = 1/15 - 1/10

1/v = 2/30 - 3/30

1/v = -1/30

v = -30cm | position.

______

size : v/u = h'/h

-30/-10 = h' / 6

180/10 = h'

18cm = h'

_______

nature is virtual as both image and object lie in the same side since both are negative.
