Chapter 4, Problem 60P

(a)

To determine

Start with Equation (4.30) use the binomial expansion to show that this transition produces a photon with wavelength approximately n3/2R.

(b)

To determine

Obtain the same result as in part (a), this time start with Equation (4.25) and compute dE/dn .

(c)

To determine

Using the approximate expression you derived in (a) and (b) compute the wavelength for a transition from n=101ton=100 in hydrogen and compare the answer with the exact wavelength for this transition computed using equation (4.30).

Required information Two speakers vibrate in phase with each other at 523 Hz. At certain points in the room, the sound waves from the two speakers interfere destructively. One such point is 1.45 m from speaker #1 and is between 2.00 m and 4.00 m from speaker #2. The speed of sound in air is 343 m/s. How far is this point from speaker #2? m
a) Consider the following function, where A is a constant. y(x,t) = A(x — vt). Can this represent a wave that travels along?
