What pipe extension do I need for lav drain?

[MJ02]

I’m a first time homebuyer with basically no experience and decided to redo a bathroom. The pipe for my new sink isn’t long enough to connect to the existing pipes. Can anyone give me a Home Depot or Lowe’s link to the connector that I need?

The black piece coming from the sink is called a sink drain pipe or tailpiece. Pull that piece off and take it to the store to find a longer one of the correct diameter (1 1/4 vs. 1 1/2) and length (you may have to cut it to length). Or, use an extender.....

NooB here

I need to replace a leaking copper waste arm under a double sink. Could I replace it with PVC pipe and connect to copper pipe (similar to the above pic) ? Do I use PVC flange to PVC and copper to copper?

I think it is simple question but have not found a straight forward answer. Thanks!
