Question
P7B.8 A normalized wavefunction for a particle confined between 0 and L in
the x direction, and between 0 and L in the y direction (that is, to a square of
side L) is y = (2/L) sin(Tx/ L) sin(Ty/L). The probability of finding the particle
between x, and x, along x, and between y, and y, along y is
P= "w°dxdy
Calculate the probability that the particle is: (a) between x = 0 and x = L/2, y =
O and y = L/2 (i.e. in the bottom left-hand quarter of the square); (b) between
x = L/4 and x = 3L/4, y = L/4 and y = 3L/4 (i.e. a square of side L/2 centred on
x = y = L/2).
