Question

Two travelling waves produces a standing wave represented by equation. y = 1 . 0 mm cos 1 . 57 cm - 1 x sin 78 . 5 s - 1 t . The node closest to the origin in the region x > 0 will be at x = . . . . . . in cm .

TestHub · Accepted Answer

At Node, y = 0 ⇒ cos 1.57 x sin 78.5 t = 0 ⇒ cos ( 1.57 x ) = 0 ⇒ 1.57 x = π 2 ⇒ x = 1 cm
