Question
A long string is composed of two different materials. The leftside has a smaller linear mass density than the right side. Thecomposite string is placed under a uniform tension, then the leftside is vibrated with a constant frequency. It is observed that thewavelength on the light string is twice that of the heavystring. 1. what is the ratio of the linear mass densities? 2. what is the ratio of the amplitudes of vibration? 3. what is the ratio of the transverse speeds? 4. what is the ratio of the propagation speeds? 5. what is the fraction of incident energy that is transmittedto the more massive string? I promise to rate you as lifesavers if youranswer is correct! A long string is composed of two different materials. The leftside has a smaller linear mass density than the right side.
