Enny Consider a two-dimensional infinite potential well with a quantized energy of (+), where n, 1,2,3.....n,= 1,2,3,..., and a represents the potential well vidth in the x and y directions. 1.THE LOWEST ENERGY LEVEL THAT THE ELECTRON MAY OCCUPY IS 2. The values of (n,ny) for the next higher energy level that is above the lowest energy level can be 3. If the electron drops from the energy level in item (ii) to the energy level in item (1), what is the wavelength of a photon that may be emitted if the work function is 0.4 V? Assume a = 5 Å 4. Let the wave function has the general form (x, y) = Asin (*) sin(). The value of A would be,
