Question
Chapter 7, Problem 1Q
To determine
The way in which amplitude of the reflected wave and incident wave changes as the barrier height is reduced.
Expert Solution & Answer
Answer to Problem 1Q
As the barrier height is reduced amplitude of transmitted wave increases while amplitude of incident wave reduces.
Explanation of Solution
Write the expression for relation between transmission probability and reflection probability.
Here,
When barrier height is reduced and potential energy is greater than particle energy then transmission probability will increase and from the above expression it can be concluded that reflection probability will decrease.
Conclusion:
Thus, as the barrier height is reduced amplitude of transmitted wave increased while amplitude of incident wave reduced.
