Two strings \( \mathrm{A} \) and \( \mathrm{B} \) with \( \mu=2 \mathrm{~kg} / \mathrm{m} \) and \( \mu=8 \mathrm{~kg} / \mathrm{m} \) respectively are joined in series and kept on a horizontal table with both the ends fixed. The tension in the string is \( 200 \mathrm{~N} \). If a pulse of amplitude \( 1 \mathrm{~cm} \)
\( \mathrm{P} \) travels in A towards the junction, then find the amplitude of reflected and transmitted pulse.
