Results are presented for JHK infrared, simultaneous ubvr, and standard UBVrR2 photometry as well as Balmer-line scanner measurements of the dwarf novae SS Cyg, RX And, Z Cam, AH Her, and AB Dra. Observed line and continuum intensities are converted to fluxes, and the flux distributions over wavelength are analyzed to determine the temperatures, densities, and contributions of each component and the disk hot spot at minimum light. The contributions of the hot spot and secondary star are obtained for each system by comparing the observed flux distributions with those expected for free-free emission from hot spots of various temperatures and for different types of main-sequence secondaries. The density of the spot is estimated to be about 10 to the 15th power per cu cm in all systems at minimum light, and the Balmer lines are found to be optically thick. It is shown that the short-period systems have the hottest spots, the length of the light period is correlated with the magnitude change from minimum to maximum, and flickering is caused by a temperature change in the spot.
