The equation of stationary wave along a stretched string is given by \( y=5 \sin \frac{\pi x}{3} \cos 40 \pi t \), where \( x \) and \( y \) are in \( \mathrm{cm} \)
\( \mathrm{P} \) and \( t \) in second. The separation between two adjacent nodes is
[MP PMT 2002; Odisha JEE 2008]
(a) \( 1.5 \mathrm{~cm} \)
(b) \( 3 \mathrm{~cm} \)
(c) \( 6 \mathrm{~cm} \)
(d) \( 4 \mathrm{~cm} \)
