Reflection refraction

In summary, to create a virtual image, one can use a convex lens and shine a light through it. The object's distance from the lens will be inversely related to the diopter rating of the lens, with a closer distance resulting in a higher diopter rating.

Homework Statement



Is it possible to move an object and a lens in such a way that the image is virtual?


The Attempt at a Solution



Well I could use a convex lens, and shine a light into it, then something would happen. The light would be angled up or angled down (depending on the position of the convex lens and the light beam).


If that is possible how would we relate where the object is with respect to the focal length of the lens?


The Attempt at a Solution



Will the The diopter rating have any relevance to my problem?

Diopter rating is D = 1/f, where f is the focal length measured in meters

. Therefore, the object's distance from the lens will be inversely related to the diopter rating of the lens. The closer the object is to the lens, the higher the diopter rating will be.
 

What is reflection?

Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.

What is refraction?

Refraction is the change in direction of a wavefront at an interface between two different media so that the wavefront enters the second medium at a different angle than it would have if it had continued in its original medium.

What causes reflection?

Reflection occurs when a wavefront encounters a change in medium, such as when it encounters a boundary between two different materials. The change in medium causes the wavefront to change direction.

What causes refraction?

Refraction occurs when a wavefront enters a medium with a different density, causing it to change direction. This is due to the change in speed of the wavefront in the new medium.

What is the difference between reflection and refraction?

The main difference between reflection and refraction is the direction of the wavefront. In reflection, the wavefront bounces back in the same medium, while in refraction, the wavefront enters a new medium and changes direction.
