When viewing an item through a convex lens, the observer will certainly always watch an upappropriate, smaller sized version, for all positions of the object.

You are watching: Is the object distance less than the focal length f, between f and 2f, or greater than 2f?

This deserve to be demonstrated as complies with.

Object at even more than `2F`

This means that the object is additionally away than two primary focal lengths from the concave lens.

*

The photo is smaller sized, upappropriate, online and in between the primary focal allude on the object side and also the concave lens.

Object at `2F`

When the object is at two primary focal points from the concave lens, you get the complying with ray diagram:

*

The picture is smaller, upbest, virtual and in between the principal focal allude on the object side and also concave lens.

Object between `2F` and also `F`

Placing the object in between two focal points and one focal suggest produces the following ray diagram:

*

The picture is smaller sized, upbest, online and in between the principal focal point on the object side and also the concave lens.

Object at `F`

When the object is inserted at the focal point of the concave lens, you obtain the complying with ray diagram:

*

The photo is smaller, upappropriate, online and also in between the principal focal allude on the object side and the concave lens.

Object in between `F` and concave lens

When the object is placed in between the principal focal suggest and also the lens, the following occurs:

*

The photo is smaller sized, upappropriate, online and between the major focal point on the object side and also the concave lens.

Conclusion

We have the right to watch from the over that for eexceptionally place of the object the image developed is always.
