What difference would it make to the photo if x-rays were not on for long enough?

If X-rays are not turned on for a long enough period, the resulting photo would be underexposed. This means that the image would appear dark and lack detail. This is because X-rays are used to create an image of the inside of an object by passing X-rays through it and capturing the resulting image. If the X-rays are not on for a long enough period, there will not be enough X-rays captured to create a clear and detailed image. This can lead to important details being missed, which could have implications for medical diagnosis or other applications where precise imaging is crucial.
