What are the essential differences between representational and abstract art/photography?
There are a few essential differences between abstract and representational photography/art. But it is also based on personal preferences as the viewer may see one image as abstract, whereas to another viewer, the image could be seen as representational.
With an abstract image there is a key thing of there being no set image. It can also contain bright colours or dark colours with no set order or style. Simply painted onto the canvas.
In photography, an abstract piece of work could have many sharp lines or curves, creating an image out of shapes or shadows with no meaning to it. There are different pieces of work which are classed as abstract photos.
For representational images, there needs to be form and shape of the image. There needs to be a subject which you can focus on, which gives it meaning.
Representational pieces of artwork could be something like a still painting, like the Mona Lisa, or it could be a still photograph of something which is representational to certain people.
There are images which borderlines both of these differences which means that it's to the personal preference of the person who is viewing the photo to decide whether to them, the image/artwork is representational or abstract.

What might Abstract photographs be good for?
In my personal opinion, I'd put abstract images or artwork pieces on display in my home. I'd display the image on the wall of a room which is regularly visited because it would capture the attention of the visitors.
Abstract photographs would also be good to create another abstract image, if you use the right style of images in the right placement.
