Chapter 2, Problem 3RQ Problem What is meant by a probability density function? Step-by-step solution Step 1 of 3 Probability density function represents probability of finding a particle at the position x and at time 1. is the probability density function. It is a real and time independent quantity. It is obtained by taking product of Schrodinger's wave function and it's conjugate. Step 2 of 3 Probability density function is represented as follows. Here, (x,t)is the complex conjugate of Step 3 of 3 For a system having motion of particle in (say) direction, probability of finding particle in whole x-axis is 1. This statement is mathematically represented as, 2 This is known as normalization condition.
