a. What is the value of $c ?$
b. Draw a graph of $|\psi(x)|^{2}$
c. What is the probability that the neutron is located between $x=-1.0 \mathrm{mm}$ and $x=1.0 \mathrm{mm} ?$

Key Concepts

Normalization of the Wave Function

In quantum mechanics, the wave function must be normalized so that the total probability of finding the particle anywhere in space is equal to one. This normalization process involves determining the constant (often denoted as c) that, when applied, ensures that the integral of the absolute square of the wave function over all space equals unity.

Probability Density

The probability density is given by the absolute square of the wave function, |?(x)|². This quantity represents the likelihood of finding the particle at a particular point in space. Its calculation and interpretation are central to understanding quantum behaviors and measurement outcomes.

Graphical Representation of Probability Density

Plotting |?(x)|² provides a visual depiction of how the probability of locating a particle varies with position. Such graphs help in identifying regions with higher or lower probabilities and can illustrate features such as peaks and nodes in the distribution.

Probability Calculation Using Integration

To find the probability of locating a particle within a specific region, one integrates the probability density |?(x)|² over that spatial interval. This integral gives the cumulative probability for the particle's presence between the set limits, reflecting the fundamental probabilistic interpretation of quantum mechanics.
