# What is the sequence of ATC frequencies for final approach at JFK?

Recently I was listening to liveATC.net and tried to understand the sequence of operations for the voice communications.

However, it seems that there are a lot of frequencies for the approach procedure, and I got confused by their names and jobs. For example, the JFK terminal has two approaches (CAMRN 128.125 and ROBER 125.700), one Final approach (Final 132.400) that I don't really know what it is, and one two Tower frequencies (123.9 and 119.1). So the question is, (1) I think the tower will be covering the final approach but what is the "Final 132.400" frequency for? (2) when and where (e.g., distance from the airport) the aircraft will be handed over from one frequency to another? Does the tower frequencies only cover up to 5 nautical miles from the airport?
