Question

For the stationary wave `y=4sin((pix)/(15))cos(96pit)`, the distance between a node and the next antinode is
A. `7.5`
B. 15
C. `22.5`
D. 30

Answer 1

Correct Answer - a
On comparing giben equation with standard
ewuation, we get `(2pi)/lambda = pi/15 rArr lambda = 30 `
Distance between the node and antinode `lambda/4=30/4=7.5`
