## Theories of Quantum Physics

**Instructions:**
Read each question carefully. Choose the answer that best fits the question. Short answer response questions must be responded to in complete sentences. If the question involves calculations, you must show all your math work.

1.

Quantum physics examines how energy and matter behave at .

- absolute zero temperature
- dynamic equilibrium
- a macroscopic level
- a microscopic level

2.

is a theory that proposes that every elementary particle exhibits the properties, not only of particles, but also of waves.

- General relativity
- Atomic Model theory
- Schrodinger's theory
- Wave-particle duality

3.

According to the Heisenberg uncertainty principle, a particle's and position cannot be known with complete precision at the same time.

- wavelength
- quantum state
- radiation
- momentum

4.

The formulas that result from string theory predict more than dimensions.

5.

Quantum is the phenomenon where a particle transitions through a barrier that it classically could not pass.

- jumping
- oscillation
- tunneling
- relocation

6.

Which of the following formed the basis for the old quantum theory?

- Bohr’s atomic model
- Schrodinger’s model
- Wien’s hypothesis
- Planck’s law

7.

Protons and neutrons are made of fundamental particles of matter called .

- atoms
- nuclei
- ions
- quarks

8.

When one object is measured, and the Schrodinger wave function collapses into a single state, the other object collapses into its corresponding state, no matter how far away the objects are, describes which theory of Quantum Physics?

- Heisenberg Uncertainty Principle
- Unified Field Theory
- Quantum Entanglement & Nonlocality Theory
- String Theory

9.

A key equation in quantum physics is the , which shows the probability of finding a particle at a particular point in space.

- Planck's constant
- Schrodinger equation
- Stefan-Botlzmann's constant
- mass-energy equivalence

10.

is a mathematical theory that tries to explain certain phenomena which is not currently explainable under the standard model of quantum physics.
