A wave moving in the positive x direction has an amplitude of 0.4 m,a frequency of 0.25 Hz,and a wavelength of 24 m.An equation,in which the units are SI,that might describe this wave is
A) y(x,t) = 0.2 sin 2 (t/4 + x/24)
B) y(x,t) = 0.4 sin 2 (t/4 - x/24)
C) y(x,t) = 0.4 sin 8 (t - x/6)
D) y(x,t) = 0.2 sin 0.5 (t/4 - x/24)
E) y(x,t) = 0.4 sin 2 (t/4 + x/6)
