Worked practice questions

Who first demonstrated electromagnetic waves experimentally?

  1. Bohr
  2. Ohm
  3. Bose
  4. Hertz
Show answer and solution

Correct answer: D. Hertz

1. Maxwell predicted the waves but did not produce them. 2. The first laboratory production came in the eighteen eighties. 3. Hertz demonstrated them experimentally. 4. So the answer is Hertz. _Source: syllabus Physics, Ch 8 'Electromagnetic Waves'_
