Green light has a wavelength of 550 nm, through what potential difference must the electrons be accelerated to have a wavelength like this?4. A particle of mass, m, is placed in a 1D-box of length, a, for which it is confined to be within the range 0 < x < a. Just after a measurement of some kind, where the system interacts with a measuring device, the final state of the system is given as (x, t = 0*) = c(e-ic 2(x) + vZe-i83(x) – $4(x)) where (dn} defines a complete set of orthonormal wave functions that solves the TISE, and a = and & = . If many experiments are performed that measure the energy on identically prepared systems, it is possible to quantify the statistical properties of possible outcomes. Answer the following questions. Part (e) is tedious and a bit time consuming. What does this integral o P¿(x) ¢n(x) dx equal to? What is the normalization constant. What is the probability for the particle to be measured in energy state n? What is the predicted average energy from many measurements of energy?
