Both the test tubes contain true solutions.
The potash alum and the salt are completely soluble in water. So the test tubes a and b are true solutions.
True solutions: These are homogeneous solutions in which the solute is completely dissolved in the solvent.
In true solutions, the light rays pass through it.
Therefore when the light is passed through both the beakers a and b, the path of light is visible but is not scattered.
