The equations of two waves are given by: \( y_{1} = 5 \sin 2\pi(x - vt) \, \text{cm} \) ; \( y_{2} = 3 \sin 2\pi(x - vt + 1.5) \, \text{cm} \) These waves are simultaneously passing through a string. The amplitude of the resulting wave is:
\( 2 \, \text{cm} \)
\( 4 \, \text{cm} \)
\( 5.8 \, \text{cm} \)
\( 8 \, \text{cm} \)
