The reflection phenomena of a plane moving shock wave on a wedge surface have been investigated by many researchers, and four different types of reflection have been observed in previous shock tube experiments. The authors have reported on the domains and boundaries of these four types of reflection and the shape of a reflected shock wave in the previous reports. In the present paper, the distribution of the strengths of a reflected shock wave along its wave front has been calculated from its shape obtained by optical observations, and the relation between the strength and the shape of a reflected shock wave has been discussed in detail. Furthermore, the flow properties around the triple point in the case of Mach reflection have been calculated using the experimental data, and the validity of the three-shock theory has been examined.
