Two waves of same frequency \(n\) are approaching each other with same velocity, \(v=20 \mathrm{~m} / \mathrm{s}\) and interfere. The distance between two consecutive nodes is
- A \(\frac{20}{n}\)
- B \(\frac{10}{n}\)
- C \(\frac{5}{n}\)
- D \(\frac{n}{10}\)
Answer & Solution
Correct Answer
(B) \(\frac{10}{n}\)
Step-by-step Solution
Detailed explanation
Distance between two consecutive nodes is given by, \(x=\frac{\lambda}{2}\).
\(x=\frac{\lambda}{2}=\frac{1}{2}\left(\frac{v}{n}\right)=\frac{20 \mathrm{~ms}^{-1}}{2 n \mathrm{~s}^{-1}}=\frac{10}{n}\)
\(x=\frac{\lambda}{2}=\frac{1}{2}\left(\frac{v}{n}\right)=\frac{20 \mathrm{~ms}^{-1}}{2 n \mathrm{~s}^{-1}}=\frac{10}{n}\)
