How Signature works under the hood to verify transaction with Public Key?

I understood that giving data and using the private key the function generates a signature key, but how the signature works under the hood to verify the transaction with the Public Key?

[Equious]

The signature is a unique hash derived from its constituent parts (Public Key and Private Key). My understanding is that the transactions verifies this unique hash with the submitted private key to authorize the wallet's transactions.

You'd have to learn more about ECDSA to understand how exactly they work at a mathematical level.
