question 100

Multiple Choice

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\(\pi\)(t/4 + x/24)
• B)y(x,t)= 0.4 sin 2\(\pi\)(t/4 - x/24)
• C)y(x,t)= 0.4 sin 8\(\pi\)(t - x/6)
• D)y(x,t)= 0.2 sin 0.5\(\pi\)(t/4 - x/24)
• E)y(x,t)= 0.4 sin 2\(\pi\)(t/4 + x/6)
