What OSI physical layer term describes the process by which one wave modifies another wave? Group of answer choicesModulationIEEEAirEIA/TIA

To address the question regarding the OSI physical layer and the modification of waves, let's analyze the terms provided in the answer choices:

1. Modulation: This is the correct term that describes the process by which one wave modifies another wave. In telecommunications, modulation involves varying a wave's properties (such as amplitude, frequency, or phase) to encode information.

2. IEEE: This refers to the Institute of Electrical and Electronics Engineers, a professional association that develops standards for electrical and electronic systems, but it does not describe a process.

3. Air: This is simply a medium through which waves can travel, but it does not imply any modification process.

4. EIA/TIA: These are organizations that develop telecommunications standards (Electronic Industries Alliance and Telecommunications Industry Association), but they do not describe a process related to wave modification.

Conclusion

The best answer to the question is Modulation, as it specifically refers to the process where one wave modifies another wave in the context of signal transmission.
