A convex lens froms a real and innert image needle at a distance of 50

1.	A convex lens froms a real and innert image needle at a distance of 50 cm from it where is the needle placed in front of convex lens if image is equal to the size of the object also find power of the lens?
Answer» Answer: here is your answer... the needle should be placed at 2F to OBTAIN a equal and inverted IMAGE. f =- 50 CM= -1/2 m P= 1/f hence POWER= 2 diopter hope it helps.

Answer:

here is your answer...

the needle should be placed at 2F to OBTAIN a equal and inverted IMAGE.

f =- 50 CM= -1/2 m

P= 1/f

hence POWER= 2 diopter

hope it helps.
