Would electromagnetic wave modulation be discovered purely visually? Can you invent a new communication mode in total absence of its key analogous sense is what is my question is?
– Asked by Lohit via Ask a Science Question
The whole purpose of early radio was to move audible information across space wirelessly. But if you remove sound entirely, what remains is a more fundamental truth that radio waves are just electromagnetic radiation. They are not sound. They are not inherently tied to our ears. They are physics. They are vibrations.
There’s no reason why a deaf person wouldn’t invent a radio. It’s basically understanding electromagnetism in the context of information transfer. Remote and wireless information transfer to be precise. Given that deaf persons are not exposed to sound since their birth here, they’d still perceive electromagnetism in the world. Hearing and sound are not required to understand it.
All concepts of transmission, fields, resonance, can be visually learned and experimented and definitely a deaf person is capable of inventing a radio without the analog exposure to the sense of sound.
