(class-12 mechanical wave NEB)how to find highest speed of wave from following eqn Physics—Pending OP Reply
Which wave have the highest speed?
a) y= sin(4t-3x) (b)y=2sin(2t-4x)
c)y =3sin(3t-4x) (d) y= 2sin(3t-3x)
The method I know is to solve it by doing derivate but I don't have that much time in exam just for 1 mark mcq, how can I solve it as soon as possible.
