Harmonic oscillator (25 marks): consider a linear harmonic oscillator with the solution de- fined by the ladder operators a and a defined in class. use the number basis in) to do the following. class. use the nuim such that (Ο x1) is as large as a) construct a linear combination of 10) and 11) to form a state l possible. b) suppose that the oscillator is in the state constructed in a) at time t = 0, write an expression to de- scribe the time dependence of this state state for t > 0. evaluate the expectation value (t) x r(t)) as a function of time for t > 0. c) defining (Ξ΄2p = (t)lx? it((t)x1r(t))2. calculate (ar)2

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.
