Consider the following standing wave, (all units are SI)
z=0.2sin(0.4y)cos(350t)
(a) The values of y where the displacement is always zero, are of the form y=a+bn, where n=0,±1,±2,3, etc.
What is a?
(b) The values of t where the displacement at all values of y equals to zero are of the form : t=c+dn, where n=0,±1,±2,3, etc.
What is c ?
what is d ?
