A scientist is working with a new kind of quantum dot to make a dye. He is applying Newton’s laws to the particle, but it seems to be breaking these laws of physics. Which action will most likely help the scientist study the particle’s motion?
Answer
A
He needs to remember that the particle is too large for quantum analysis.
B
He needs to use quantum mechanics, not Newtonian mechanics, because this is a nanotechnology product.
C
He must determine new physical laws that only apply to quantum dots.
D
He must continue to use Newtonian mechanics, but he needs to learn more about the particle.
Explanation
Quantum dots are nanoscale particles, so their behavior is governed by quantum mechanics rather than classical Newtonian mechanics alone. To study the particle’s motion, the scientist should use quantum mechanics. Choice A is wrong because a quantum dot is small enough for quantum effects to matter.
