8-1 Two strings, of tension T and mass densities 1 and 2, are connected together. Consider a traveling wave incident on the bound- ary. Find the ratio of the reflected amplitude to the incident amplitude, and the ratio of the transmitted amplitude to the incident amplitude, for the cases 2/μ₁ 0, 0.25, 1, 4, 0. =

In quantum mechanics, Schrödinger’s equation for certain systems with varying parameters cannot be solved directly. In such a case, an approximation method is used to obtain the approximate solution. WKB method is a special technique used to obtain the a…
