• Stopwatch

Who was Werner Karl Heisenberg?

• A British mathematician

• A German theoretical physicist

• An American inventor

• A French chemist

What principle did Heisenberg introduce in 1927?

• Schrodinger's Cat Theory

• Heisenberg Uncertainty Principle

• Quantum Entanglement

• Theory of Relativity

According to the Heisenberg Uncertainty Principle, what can't be measured simultaneously with absolute precision?

• Temperature and Pressure

• Position and Momentum

• Energy and Mass

• Time and Space

What discovery did Albert Einstein contribute to the field of quantum mechanics?

• Black Holes

• Wave-Particle Duality of Light

• Theory of General Relativity

• E=mc^2

What experiment supported the wave-particle duality of light?

• Rutherford's gold foil experiment

• Michelson-Morley experiment

• Compton scattering

• Double-slit experiment

Why can't we see waves around macroscopic objects in our everyday life?

• Because light doesn't interact with them

• Because they are not made of particles

• Because they move too slowly

• Because their wavelengths are too small

What happens when a photon bounces off an electron?

• The electron stops moving

• The photon's energy decreases

• The electron's path changes

• Nothing happens

What does the Heisenberg Uncertainty Principle state about measuring the position and momentum of a particle?

• It's easier for larger particles

• It's impossible to do both accurately at the same time

• It can be done with high precision

• Only momentum can be measured accurately
