Two travelling waves produces a standing wave represented by equation,
y = 1.0 mm cos(1.57 cm$-$1) x sin(78.5 s$-$1)t.
The node closest to the origin in the region x > 0 will be at x = .............. cm.
Answer (integer)
1
Solution
For node<br><br>cos(1.57 cm<sup>$-$1</sup>)x = 0<br><br>(1.57 cm<sup>$-$1</sup>)x = ${\pi \over 2}$<br><br>x = ${\pi \over {2(1.57)}}$ cm = 1 cm
