Which phenomenon is a clear evidence of the wave-particle duality of light?

• Refraction of light

• Photoelectric effect

• Total internal reflection

• Dispersion of light

The Heisenberg uncertainty principle states that:

• The position and velocity of a particle can be precisely determined simultaneously.

• Energy and time are unrelated.

• There is a fundamental limit to the accuracy with which we can simultaneously measure the position and momentum of a particle.

• All particles move at the speed of light.

Quantum entanglement is:

• The interaction between particles that are far apart.

• A special connection between particles, causing the state of one particle to depend on the state of another, regardless of the distance between them.

• The superposition of quantum states.

• The process of one particle transforming into another.

In the Bohr atomic model, electrons move around the nucleus on orbits:

• Any.

• Only those orbits with defined energy.

• Only circular orbits.

• Only elliptical orbits.
