Questions and Correct Answers | New

What is Quantum Physics? - 🧠 ANSWER ✔✔Quantum physics is a branch
of science that deals with discrete, indivisible units of energy called quanta
as described by the Quantum Theory.
Quantum Theory - 🧠 ANSWER ✔✔There are five main ideas represented in
Quantum Theory:
1.Energy is not continuous, but comes in small but discrete units.
2.The elementary particles behave both like particles and like waves.
3.The movement of these particles is inherently random.
4.It is physically impossible to know both the position and the momentum of
a particle at the same time. The more precisely one is known, the less
precise the measurement of the other is.
5.The atomic world is nothing like the world we live in.

, Particle/Wave Duality - 🧠 ANSWER ✔✔Particle/wave duality is perhaps the
easiest way to get aquatinted with quantum theory because it shows, in a
few simple experiments, how different the atomic world is from our world.
The Copenhagen Interpretation - 🧠 ANSWER ✔✔So sometimes a particle
acts like a particle and other times it acts like a wave. So which is it?
According to Niels Bohr, who worked in Copenhagen when he presented
what is now known as the Copenhagen interpretation of quantum theory,
the particle is what you measure it to be. When it looks like a particle, it is a
particle. When it looks like a wave, it is a wave. Furthermore, it is
meaningless to ascribe any properties or even existence to anything that
has not been measured. Bohr is basically saying that nothing is real unless
it is observed.
While there are many other interpretations of quantum physics, all based
on the Copenhagen interpretation, the Copenhagen interpretation is by far
the most widely used because it provides a "generic" interpretation that
does not try to say any more then can be proven. Even so, the
Copenhagen interpretation does have a flaw that we will discuss later. Still,
