 $e^{πi\ }$  =

• 1

• infinity

• -1

• none of the above

Which unified theory do you support?

• String theory/M-theory

• Supergravity theory

What's the name of the infamous experiment in Quantum Physics?

• Double-Split Experiment

• One-Slit Experiment

• Double-Decker Experiment

• Double-Slit Experiment

The minimum energy required by a bound electron to be liberated from the metal when it is illuminated by light of suitable wavelength is called

• Stopping potential

• threshold frequency

• work function

• maximum kinetic energy

The photoelectric effect only occurs if the light shining on the metal is:

• coherent.
• above a minimum intensity.
• above a minimum frequency.
• above a minimum wavelength.

Wave -particle duality is supported by...

• electrons behaving as particles with ordinary matter

• electrons behaving as waves when travelling through space

• the photo electric effect

• all of the above

The Heisenberg Uncertainty Principle said that one cannot know

• the speed of light in a vacuum.

• the number of energy levels in a very large atom.

• both the wavelength and frequency of a photon at the same time.

• both the velocity and the position of a particle at the same time.

What is the most massive particle in quantum physics?

(a)  

What is a fractal?

The solutions of the quadratic equation 
x²+2x-15=0 are

• x = 3 or x = 5
• x = 5 or x = -3
• x = -5 or x = 3
• x = -3 or x = -5
