Two travelling waves produces a standing wave represented by equation, y=1.0 mm cos (1.57cm^-1 ) sin (78.5s^-1 )t The node closest to the origin in the region x0 will be at x=……. cm.

Question

Two travelling waves produces a standing wave represented by equation, y=1.0 mm cos (1.57cm^-1 ) sin (78.5s^-1 )t The node closest to the origin in the region x>0 will be at x=……. cm.

Accepted Answer

Correct answer: 1. (1) For node cos (1.57cm^-1 )x=0 (1.57cm^-1 )x= 2 x= 2 (1.57 ) cm=1 cm

$Two travelling waves produces a standing wave represented by equation, y = 1.0 mm cos (1.57 c m^{- 1}) \times sin (78.5 s^{- 1}) t The node closest to the origin in the region x>0 will be at x=\dots\dots. cm.$
