A line
Yes, a ray has only one endpoint.
A ray can be described as the half line with designated end point which extends in only one direction without stopping.
Such a figure cannot exist. If it goes on forever in only one direction then it must have an end point.

A ray has only one point. It goes on and on in one direction only.

No. A doctor listens for it. Pneumonia shows up on the x ray.
To draw a ray in a geometric figure, start by drawing a straight line. Then, draw a point on one end of the line to represent the starting point of the ray. Finally, draw an arrow on the other end of the line to show the direction the ray extends infinitely.
Yes. An x-ray shows only bones; an MRI shows bones+tissues+muscle.
