Understanding Quantum Mechanics

How do quantized properties in quantum mechanics differ from classical mechanics?

• They are always visible.

• They are unpredictable.

• They occur in set amounts.

• They occur in continuous amounts.

What was initially disbelieved about the nature of light?

• That it could change color.

• That it could travel faster than sound.

• That it could be classed as a particle.

• That it could behave as a wave.

Who were the scientists that proposed the wave-like nature of matter?

• Max Planck and Werner Heisenberg

• Isaac Newton and Galileo Galilei

• Albert Einstein and Niels Bohr

• Louis De Broglie and Erwin Schrodinger

What happens to electrons when they are observed in a quantum experiment?

• They behave like waves.

• They disappear.

• They behave like particles.

• They change color.

In the experiment described, what effect does increasing the observer's capacity have on electron interference?

• It changes the color of electrons.

• It weakens the interference.

• It has no effect.

• It strengthens the interference.
