Answer each question with a minimum of 100 hundred words.
1. Can you think of a few of our modern day technology which would not work without the quantum theory being true?
2. Can larger objects like stones and airplanes flying at a great speed exhibit wave properties?
3. Do you think that it is only the electrons that behave in such a way whereby they could be conceived as waves or particles, or would ordinary matter, strictly speaking, be also considered exhibiting the wave particle duality? How does the wave characteristic of matter differ from the particle characteristic? Can we also envision an atom to be a wave or a particle?
