The stationary wave produced on a string is represented by the equation y=5cos(πx/3)sin40πt. Where x and y are in cm and t is in seconds. The distance between consecutive nodes is 

(1) 5 cm

(2) π cm

(3) 3 cm

(4) 40 cm

(3) On comparing the given equation with standard equation 2πλ=π3λ=6cm.

Hence, distance between two consecutive nodes ⇒ λ = 3 cm
