Physics Trivia Quiz Questions And Answers

What is particle physics?
A: Particle physics is a branch of physics which studies the nature of particles that are the constituents of what is usually referred to as matter and radiation.

What is modern particle physics research focused on?
A: Subatomic particles.

Dynamics of particles is also governed by what?
A: Quantum mechanics.

The particles exhibit wave–particle duality, displaying particle-like behavior under certain experimental conditions and what behavior in others?
A: Wave-like.

In more technical terms, they are described by what?
A: Quantum state vectors in a Hilbert space.

The term "elementary particles" is applied to those particles that are, according to current understanding, presumed to be what?
A: Indivisible and not composed of other particles.

All particles, and their interactions observed to date, can be described almost entirely by what theory?
A: A quantum field theory called the Standard Model.


The Standard Model, as currently formulated, has how many elementary particles?
A: 61.

Elementary particles can combine to form  what?
A: Composite particles.

The Standard Model has been found to agree with almost all the what?
A: Experimental tests conducted to date.

However, most particle physicists believe that it is an incomplete description of what?
A: Nature, and that a more fundamental theory awaits discovery.

The idea that all matter is composed of elementary particles dates to at least how far back?
A: The 6th century BC.

In the 19th century, John Dalton, concluded that each element of nature was composed of a what?
A: A single, unique type of particle.

What does the word atom, denote?
A: The smallest particle of a chemical element at the time.


Scientists discovered that atoms are not, in fact, the fundamental particles of nature, but conglomerates of what?
A: Even smaller particles, such as the electron.

Throughout the 1950s and 1960s, what was found in scattering experiments?
A: A bewildering variety of particles.

It was referred to as the what?
A:  "particle zoo".

That term was deprecated after the formulation of the Standard Model during the 1970s in which the large number of particles was explained as what?
A: Combinations of a (relatively) small number of fundamental particles.

The current state of the classification of all "what" is explained by the Standard Model?
A: Elementary particles.

It describes the strong, weak, and electromagnetic fundamental interactions, using what?
A: Mediating gauge bosons.

The species of gauge bosons are the gluons, W−, W+ and Z bosons, and the what?
A: Photons.
