Ariel claims that a pulse is described by the equation where x and y are measured in cm and t in s. Miranda says that it is not possible to represent a pulse with this function because a wave must be a function of x + vt or x − vt. Which one, if either, is correct, and why?
A)Ariel, because x2 - 6.0xt + 9t2 = (x - 3.0t)2.
B)Ariel, because a pulse is not an infinite wave.
C)Miranda, because (x - 3.0t)2 is the same as (3.0t - x)2.
D)Miranda, because a pulse is not an infinite wave.
E)Miranda, because is infinite when x = 0.
