A water "light pipe" is created by a stream of water exiting a container through a hole with a circular cross section of diameter d=5mm. Lascr light is injected uniformly into the water stream through the hole as shown. If the water and laser light exits the container initially horizontally with a laminar flow, and we approximate the trajectory of the water as following a circular path (it would actually be parabolic) and maintaining a constant diameter for the "light pipe", find the smallest outside radius R permitted for the water path such that no laser light escapes on its first reflection with the water-air surface. Water has an index of refraction of n=1.33.

Extrasolar Planets. In the not-too-distant future, it should be possible to detect the presence ofplanets moving around other stars by measuring the Doppler shift in the infrared light they emit. If a planetis going around its star at 50 km/h while emitting infrared light of frequency 3.330 x 1014 Hz, whatfrequency light will be received from this planet when it is moving directly away from us? (Note: Infraredlight is light having wavelengths longer than those of visible light.)

Whereas electron microscopes make use of thewave properties of electrons, ion microscopes make use of the wave propertiesof atomic ions, such as helium ions 1He+2, to image materials. A heliumion has a mass 7300 times that of an electron. In a typical helium-ionmicroscope, helium ions are accelerated by a high voltage of 10–50 kVand focused into a beam onto the sample to be imaged. At these energies,the ions don’t travel very far into the sample, so this type of microscopeis used primarily for the surface imaging of biological structures. The useof helium ions with much greater energies (in the MeV range) has beenproposed as a way to image the entire thickness of a sample, becausethese faster helium ions can pass all the way through biological samplessuch as cells. In this type of ion microscope, the energy lost as the ionbeam passes through different parts of a cell can be measured and relatedto the distribution of material in the cell, with thicker parts of the cellcausing greater…
Problem 4.43 (a) Construct the spatial wave function () for hydrogen in the state n = 3, l1 = 2, m = 1. Express your answer as a function of r, 0, 4, and ä (the Bohr radius) only-no other variables (p, z, etc.) or functions (Y, v, etc.), or constants (A, Co, etc.), or derivatives, allowed (7 is okay, and e, and 2, etc.). %3D (b) Check that this wave function is properly normalized, by carrying out the appropriate integrals over r, 0, and ø.
