(#M40027544) AIEEE question Mental Ability Keep an EYE

Sinusoidal waves travel on four different strings,
all with the same tension. Three of the strings
have the same linear mass density, but the fourth
has a different linear mass density. Use the
mathematical forms of the waves, given below,
to identify the string with the different linear
mass density. In the expressions x and y are in
centimeters and t is in seconds -
(A) y(x, t) = (2 cm) sin(2x − 4t)
(B) y(x, t) = (2 cm) sin(4x − 10t)
(C) y(x, t) = (2 cm) sin(6x − 12t)
(D) y(x, t) = (2 cm) sin(8x − 16t)
