In refraction seismology as well as in global seismology we often find travel-time diagrams where reduced time is used. In principle this means that the refraction arrival of interest is approximately horizontal in the travel-time diagram. This can be achieved by doing the following transformation red red v t t ∆ =− (14)

no longer confined to the science laboratory. Meaning of Research: Word Research is comprises of two words = Re+Search. It means to search again. So research means a systematic investigation or activity to gain new knowledge of the already existing facts. Research is an intellectual activity. It is responsible for bringing to light new knowledge.
