Physics - Wave on String Question with Solution | TestHub

Two strings AB and BC of length 1 meter and $1/2$ meter respectively are joined together at end B as shown. Point B is the junction of both strings. The mass per unit length of string AB and BC are 0.16 kg/m and 0.25 kg/m respectively. A tension of 100 N is maintained in both the strings. A sinusoidal wave pulse of amplitude 2 mm is produced at end ' A '. It is partly reflected and partly transmitted at joint B . Find the ratio of amplitudes of transmitted and reflected waves.
