We were in the final phase of the flight. Captain announced our descent and advised the Flight Attendants to prepare cabin for arrival; seat belt sign was turned ON and Flight Attendant A made the arrival announcement. I was securing my beverage cart when 2 passengers approached me in the aft galley: Passenger A asked to use the LAV; I advised her that the LAV was occupied [Passenger C]. Passenger B asked me for another drink. I advised him that my cart was secured and we were making our descent. (He appeared agitated; so I told him I would try to accommodate him as best as I could given the amount of time remaining.) It was at that time the aircraft was hit by turbulence. Passenger A was thrown onto the galley floor and she landed on her back. I was thrown into R2 and landed on my left shoulder and my left forearm hit the door handle. Passenger B was able to brace himself then helped Passenger A up from the floor. I asked Passenger A if she was alright and she said 'yes' (although clearly shaken). I advised everyone to return to their seat immediately. I asked Passenger A if she was able to walk back to her seat unaided and she said she was. I secured myself in my jump seat. Captain called on the interphone to advise we had just flown into the wake of another aircraft. He asked if everyone was OK and I advised him that a passenger had fallen on the galley floor and I was thrown into R2. I advised the Captain that I would have to file a [report] since the incident involved a possible passenger injury. Captain and I confirmed the seatbelt sign was ON during the event. Passenger C in the LAV exited and I asked her if she was ok; she assured me she was fine then returned to her seat. I approached Passenger A and got her identifying information for my incident report. I asked her again if she was okay and she said she was fine. My intent was to address Passenger B as well; but at that time I heard the second double hi-low; so I had to complete my compliance and get back into my jump seat. Unfortunately; after landing; I could not reach Passenger B to get identifying information from him.
Flight Attendant reported that wake turbulence during approach caused injury to herself and two passengers.
