L30 TRACON controller reported they issued a wrong frequency to an emergency aircraft on a vector causing it to be NORDO and it flew below the minimum vectoring altitude.

Narrative:
I was working departures. Aircraft X departed and then told me they had a cargo door issue and needed to return. I cleared them back to las via radar vectors. I told the supervisor. I handed off the aircraft to the final sector. I climbed the aircraft to 6;300 feet to comply with the MVA (minimum vectoring altitude). I gave aircraft X a 210 heading and switched him to the finals sector. I did not realize I gave him the wrong frequency. I said 135.1 not 135.0. I didn't know this until I listened to the replay. We tried on guard and everyone in the room tried on their frequency to get contact with the aircraft. He went into a 6;500 foot MVA and then a 7;000 foot; and then an 8;300 foot MVA before the adjacent approach said they had the aircraft and they were switching him to us. The final controller climbed and turned the aircraft out of the higher mvas. I should have given the correct frequency and made sure they had it before letting them go. I should have known that they went to 135.1 and reached out to the facility who owns that frequency for help before the aircraft got into those higher mvas.

Title: L30 TRACON Controller reported they issued a wrong frequency to an emergency aircraft on a vector causing it to be NORDO and it flew below the Minimum Vectoring Altitude.
Narrative: I was working Departures. Aircraft X departed and then told me they had a cargo door issue and needed to return. I cleared them back to LAS via radar vectors. I told the supervisor. I handed off the aircraft to the final sector. I climbed the aircraft to 6;300 feet to comply with the MVA (Minimum Vectoring Altitude). I gave Aircraft X a 210 heading and switched him to the finals sector. I did not realize I gave him the wrong frequency. I said 135.1 not 135.0. I didn't know this until I listened to the replay. We tried on guard and everyone in the room tried on their frequency to get contact with the aircraft. He went into a 6;500 foot MVA and then a 7;000 foot; and then an 8;300 foot MVA before the adjacent Approach said they had the aircraft and they were switching him to us. The final Controller climbed and turned the aircraft out of the higher MVAs. I should have given the correct frequency and made sure they had it before letting them go. I should have known that they went to 135.1 and reached out to the facility who owns that frequency for help before the aircraft got into those higher MVAs.
