Describes the necking of polymer sheets that occurs when they are stretched. Discusses the effect and the mechanisms of necking. Lists four references. (YP)

Describes an experiment that allows the students to verify the assumption that light travels in straight lines. (GS)

Mathematically analyzes the polarization of rainbows, a phenomenon which can be demonstrated in a laboratory simulation using polaroid sheets, perspex discs, and a white light source. (MLH)

Presents notes on three physics experiments on (1) light and lenses, (2) determination of the pVT surface of a freon, and (3) use of an eyepiece with microscopes and telescopes. (RH)

Describes a simple experiment to verify the reflectivity equations of Fresnel and for measurement of optical constants. (SL)

Describes an experiment in which a 500-A-thick silver film is evaporated on the hypotenuse face of a right glass prism. The surface plasmon mode in the film is excited with a He-Ne laser. The dispersion relation for the surface plasmon and the reflectivity due to the excitation of this mode are calculated. (Author/MLH)

Describes a laboratory experiment in which the experimental data agree well with the empirical law. Demonstrates that transparent materials reflect light. (CP)

Describes an activity involving a transparent water filled box and a plane mirror in which the refraction of light rays is demonstrated. (CP)

Presents a simple method of analysis in which the student can integrate, point by point, any interferogram to obtain its Fourier transform. The manual technique requires no special equipment and is based on relationships that most undergraduate physics students can derive from the Fourier integral equations. (Author/MLH)

In this simple experiment for an undergraduate laboratory a laser beam is passed through the mixing zone of two liquids with different refractive indices. The spatial variation of the refractive index, at different times during the mixing, can be determined from the observed deflection of the beam. (Author)

Includes description of a light meter, photometer, fluid flow apparatus, and acoustic grating. (RH)
