What did Alexander Popov achieve in 1895?

Explanation:
Wireless signals can travel through the air, and in 1895 Popov demonstrated that idea in a tangible way. He built a setup that could generate radio waves with a spark-gap transmitter and detect them with a receiver, showing that signals could be sent and understood over a distance—about 600 yards. This proved that information could move without wires, a foundational step for wireless telegraphy and later radio development. That’s why the other options don’t fit: the Audion tube came later (early 1900s) and advanced amplification rather than this early distance demonstration; establishing CBS happened long after this era; and a court case isn’t what Popov is known for.
