$\mathrm{A} \frac{\lambda}{2}$ section of a $600 \; \Omega$ transmission line, short circuited at one end and open circuited at the other end, is shown in the figure is $100 \mathrm{~V} / 75 \; \Omega$ generator is connected at the mid point of the section as shown in the figure. Find voltage at the open circuited end of the line.
