Question
From the mathematical functions in the list below, select those which correspond to each of the five motions below. For example, if functions A and G satisfy motion 1, function C satisfies motion 2 and none of the functions satisfies motions 3, 4 and 5, enter AGCNNN. (Note that the answers for each motion must be in alphabetical order.)
A) y(x,t) = 0.4 sin(2x)cos(2t/6)
B) y(x,t) = 0.8/(2+(3x+9t)2)
C) y(x,t) = 0.4 sin(x3t)
D) y(x,t) = 0.4
E) y(x,t) = 0.4/(2+(2x6t)2)
F) y(x,t) = 0.2 cos(12t4x+)
G) y(x,t) = 0.2/(1+(x3t)2) - 0.2/(1+(x+3t)2)
H) y(x,t) = 0.8 cos(2x6t+/2)
N) none of the above
1) A motion in which the medium has a wavenumber of 3 m-1.
2) A harmonic travelling wave with a period of 3 seconds.
3) A motion in which the movement of the medium corresponds to a wavelength of 1 m.
4) A standing wave that causes the medium to oscillate at a frequency of 3 Hz.
5) A motion in which the medium is stationary at all positions and for all times.
