Share:
- 1It is a purely quantum wave-mechanical phenomenon that lacks any valid classical mechanics analogue.
- 2It results in a temporary structural violation of the fundamental law of conservation of energy at microscopic scales.✓
- 3The mathematical probability of tunneling depends exponentially on both the physical width and the energy height of the barrier.
- 4It enables a microscopic particle to penetrate a potential energy barrier even when its kinetic energy is lower than the barrier height.
Correct answer
It results in a temporary structural violation of the fundamental law of conservation of energy at microscopic scales.
