Question

Stationary waves of frequency $300Hz$ are formed in a medium in which the velocity of sound is $1200metre/sec$. The distance between a node and the neighbouring antinode is

• A. $1m$
• B. $2m$
• C. $3m$
• D. $4m$

Answer 1

The correct option is A $1m$

Required distance = $\frac{\lambda }{4}=\frac{v/n}{4}=\frac{1200}{4\times 300}=1m$
