Answer» The correct option is (d) 2.5 to 5 s Explanation: Without a long persistence screen, ONE can only see a moving dot of light INSTEAD of a continuous trace. Typically for a 13-cm screen, total sweep time is USUALLY kept as 2.5 or 5 s. In this way, one can observe at least four heart beats in a single sweep PERIOD.
