Now, consider the wave function ψ(x)=ceκx+de−κx in the region x<0. as x goes to negative infinity, this must become zero. wha
Mice21 [21]

Answer:

d is zero (0)

Explanation:

ψ(x)=ce^κx+de^−κx

Let say x = - 1000

We have something like

ce^κ* -1000 = approximately zero

Where we assume k to be 1

C becomes zero as it tend to negative infinity

But

If k is 1

de^−1* 1000 =d * 2 * 10^434

To have a zero function d = 0

So 0 * 2 * 10^434 = 0
