In a physics laboratory, a student sets up two simple pendulums, Pendulum \(X\) and Pendulum \(Y\). Both pendulums consist of a light string of length \(L\) attached to a fixed support. Pendulum \(X\) has a bob of mass \(M\), while Pendulum \(Y\) has a bob of mass \(2M\). Both bobs are displaced by the same small angle and released from rest. How does the period of Pendulum \(Y\), \(T_Y\), compare to the period of Pendulum \(X\), \(T_X\), and why?
