Question

when an object is placed at 2f1 of a convex lens its image is formed .............. a) at F1 ,b) at 2F2 ,c) beyond 2F2, d) no do same side​

Answer 1

Answer:

At 2F2

Explanation:

1. If object placed at 2F same size as the object image formed at 2F2.
2. Image formed is real and inverted.

Answer 2

In a convex lens for an object which is placed at 2f1 its image is formed b) at $2F_2$.

Explanation:

• In the cases of lenses, image is formed by the phenomenon called refraction of light.
• Based upon the position of the object, its place of image formation depends.
• As per the given scenario when the object is placed at $2F_1$, its image is formed at $2F_2$ which is of the same size as the original object.
• Thus it is inferred that the correct option for the given question is option (b) at $2F_2$.
