The lowest energy of a particle in an infinite one-dimensional well is 4,4 eV. if the width of the well is doubled, what is its lowest energy?

Calculate the probability and probability density to find the particle between X = 0 and X = a /n when it is in the n state

The energies in a 2D particle-in-a-box are given by h² 8mL 2 in which the box is a square enclosure with Lx = Ly = L, and nx, ny = 1, 2, 3,... . (a) If the particle is an electron and L = 300 pm (assume three significant figures), find the value of the lowest energy level in units of 10-18 J (that is, if the energy is 5.00 × 10-18 J, you would report it as "5.00").
