Question

Consider the wave function y(x)-Find the probability of fi in the range -a

Answer 1

Answer:$(y(x))^{2}$

Explanation:

The probability of fi in a range is given by the integral, whose limits are the range limits, of the square of the wave function y(x).

Example:

let's say range [a,b] with wave function y(x), then

$Prob(a\leq x\leq b)=\int\limits^b_a {y(x)^{2} } \, dx$
