Stationary wave ?
The answer is B but how to solve it?
Could anyone give my some tips to solve this type of question?....

The distance between two nodes is a half wavelength (a "bump").
Your x is 3 bumps, or, 1.5 wavelengths = 1.5λ.
But c = λf --> λ = c/f.
Thus x = 1.5λ = 1.5 * c/f.
You are given c & f. Compute. Done!
Don't forget to vote BA.
