Which OSI physical layer term describes the process by which one wave modifies another wave?

Explanation:
Modulation. In the physical layer, information is carried by altering a carrier wave to encode the data. This change can be in amplitude, frequency, or phase, producing a modulated signal that travels over the medium. Modulation lets the signal fit the channel’s bandwidth and distance constraints and helps distinguish transmissions from noise. The other terms point to standards bodies or the transmission medium rather than the signaling method used to encode data.
