Question

Draw the ray diagram when an object is placed at twice of the focal length of a convex lens.​

Answer 1

$<I>$

its just a rough image ...

position of image : formed at 2F2

nature of image : real and inverted

❣️hope this helps uh ❣️

Answer 2

Answer:

The Image generated in this case will be the same size as the object,  

real and inverted.

Explanation:

Refraction is a wave feature that determines how a lens forms an image. It is described as the bending of waves as they enter a medium with a different speed.

• When an object is put in the centre of a lens's curvature, a ray of light that is parallel to the principal axis after refraction passes through the focus $F$ with the direction, while the other ray passes through the optical centre and proceeds straight without deviating.
• So these two refracted light beams intersect at the centre of curvature $2F$ on the other side of the lens, and the picture generated in this case will be the same size as the object, real and inverted.
