Final answer:
The emitted electrons in the photoelectric effect cannot be called cathode rays as they possess different properties.
Step-by-step explanation:
In the context of the photoelectric effect, the emitted electrons cannot be called cathode rays. The term 'cathode rays' refers to the form of energy emitted from the cathode, or negatively charged electrode, in a cathode ray tube.
These rays consist of charged particles and can be deflected by magnetic or electric fields. On the other hand, photoelectrons are emitted from a target material (cathode) when it is illuminated by monochromatic radiation, and they are collected at the anode.
They do not possess the same properties as cathode rays.
