Wave Mechanics Question 715

Question: Two waves are approaching each other with a velocity of 16 m/s and frequency n. The distance between two consecutive nodes is

[CPMT 2001; Pb. PMT 1999]

Options:

A) $ \frac{16}{n} $

B) $ \frac{8}{n} $

C) $ \frac{n}{16} $

D) $ \frac{n}{8} $

Show Answer

Answer:

Correct Answer: B

Solution:

Distance between two nodes = $ \frac{\lambda }{2} $

$ =\frac{v}{2n}=\frac{16}{2n}=\frac{8}{n} $
