Waves can also be separated into transverse and longitudinal waves. In a transverse wave, the motion of the particles of the medium is at right angles (i.e., transverse) to the direction the wave moves.
The experiment's name comes from the Tuskegee Institute, the black university founded by Booker T. Washington. Its affiliated hospital lent the PHS its medical facilities for the study, and other predominantly black institutions as well as local black doctors also participated.
Introduction. Born a slave on a Virginia farm, Washington (1856-1915) rose to become one of the most influential African-American intellectuals of the late 19th century. In 1881, he founded the Tuskegee Institute, a black school in Alabama devoted to training teachers. Washington was also behind the formation of the National Negro Business League 20 years later, and he served as an adviser to Presidents Theodore Roosevelt and William Howard Taft.
