Wave Mechanics Question 711
Question: Two waves are approaching each other with a velocity of 20 m/s and frequency $ n $ . The distance between two consecutive nodes is
[Pb. PMT 1999]
Options:
A) $ \frac{20}{n} $
B) $ \frac{10}{n} $
C) $ \frac{5}{n} $
D) $ \frac{n}{10} $
Show Answer
Answer:
Correct Answer: B
Solution:
Distance between the consecutive node $ =\frac{\lambda }{2}, $ but $ \lambda =\frac{v}{n}=\frac{20}{n} $ so $ \frac{\lambda }{2}=\frac{10}{n} $
