Homework 4
Thursday 8 February - Due: Thursday 15 February
1. Use your lab4 final code to investigate the motion of waves in 1d with differing initial
conditions. Specifically, replace the pulse boundary conditions with new ones in which
the initial displacement of mass itakes the form (all velocities can be taken zero
initially)
xi= sin ( nπi
N+ 1)
where n= 1,2,3,...What do you notice ? Does the motion correspond to a travelling
wave ? These are called the normal nodes of the system with these boundary conditions.
