Question

what is potential barrier? ​

Answer 1

Answer:

In quantum mechanics, the rectangular potential barrier is a standard one-dimensional problem that demonstrates the phenomena of wave-mechanical tunneling and wave-mechanical reflection.

Explanation:

A region within a force field in which the potential is significantly higher than at points either side of it, so that a particle requires energy to pass through it.

Answer 2

Answer:

a region within a force field in which the potential is significantly higher than at points either side of it, so that a particle requires energy to pass through it.
