A single lens is mounted in a tube. A parallel beam enters the tube and emerges out of the tube as a divergent beam. Can you say with certainty that there is a diverging lens in the tube?

Of course, we can say. Only reflection of light does not create divergence, it needs refractive index changes to diverge. Hence, there certainly is a diverging lens.
