Quiz Answer Key and Fun Facts

Answer: Light

Light is one of the principal forms of energy, and many experiments, such as the double-slit experiment and Einstein's photoelectric effect, helped to understand the true nature of light, as packets of energy called 'photons'.

2. Who famously postulated the equivalence between momentum and wavelength, essentially stating that every particle has an associated wave nature?

Answer: De Broglie

Louis De Broglie's equivalence is one of the most central concepts in modern physics.

3. Popularly known as the EPR paradox, the discussion over the nature of quantum 'quirks' such as entanglement led to a series of debates between which famous scientists?

Answer: Einstein and Bohr

Einstein argued that Bohr's interpretation of quantum mechanics was correct, yet incomplete. However, several decades later, it was Bell who settled this debate.

Answer: Spin

The spin is associated with a component of the angular momentum of a particle, and the concept of symmetry forms one of the cornerstones of quantum physics.

5. Which is NOT one of the four quantum numbers used to describe an electron?

Answer: Rotational

The four quantum numbers are principal, azimuthal, magnetic and spin.

6. One of the fundamental properties of quantum physics is the superposition of states. Which animal did Schrodinger use in his famous thought experiment to demonstrate this principle?

Answer: Cat

The end result of the experiment being that, until measurement, the cat is in a superposition state of both 'dead' and 'alive' at the same time.

7. What is the fundamental unit of energy, with regards to light?

Answer: Photon

The photon represents a packet of energy, given by the famous relation E=hf where h is Planck's constant and f is the frequency.

8. As a symbol of the smallest unit of energy, which of these plays a pivotal role in quantum physics?

Answer: Planck's Constant

Planck's constant, often denoted by h, represents the smallest unit energy can take since, in quantum physics, energy is discretized.

Answer: Tunneling

Tunneling is seen in many devices such as the tunnel diode and the scanning tunneling microscope.

10. As a proof of the successful applications of quantum physics, which multinational organization 'scribed' its name using atoms posing as the world's smallest advertisement?

Answer: IBM

IBM wrote the name 'IBM' using atoms on a thin film. IBM also released a video created by manipulating atoms. These techniques are usually achieved using atomic force microscopy.
