Question

how can you obtain an image by using lens​

Answer 1

Answer:

Explanation:

A convex lens can form real and inverted image. When the object is placed very close to the lens, the image formed is virtual, erect and magnified. When used to see objects magnified, the convex lens is called a magnifying glass. A concave lens always forms erect, virtual and smaller image than the object.

Answer 2

Answer:

You will need an object at either infinity or at C1 or between C1 and F1 or between F1 and P.

The image will be point sized when placed at infinity

It will be diminished when placed at C1.

If placed between C1 and F1 the image will be almost the same length as object.

If placed between F1 and P the image will be large or sometimes the image will form behind the lens
