A transverse wave of amplitude `0.5 m` and wavelength 1 m and frequency 2 Hz is propagating in a string in the negative x – direction. The expression for this wave is [
A. `y(x,t) = 0.5 sin (2pix – 4pit)`
B. `y(x,t) = 0.5 cos (2pix – 4pit)`
C. `y(x,t) = 0.5 sin (pix – 2pit)`
D. `y(x,t) = 0.5 cos (2pix – 2pit)`
A. `y(x,t) = 0.5 sin (2pix – 4pit)`
B. `y(x,t) = 0.5 cos (2pix – 4pit)`
C. `y(x,t) = 0.5 sin (pix – 2pit)`
D. `y(x,t) = 0.5 cos (2pix – 2pit)`
