Question

an object kept in 10cm from the convex lens calculate the image distance if the focal length is 2cm

Answer 1

Answer:

2.5 cm

Explanation:

1/f = 1/u +1/v

1/2= 1/10+1/v

1/v= 1/2-1/10

= 4/10

= 2/5

=> v= 5/2 =2.5 cm from the lens

=> image formed between focus and

centre of curvature .

hope this helps you
