Question

The distance between a node and an anti-node is

• A. $2\lambda$
• B. $\lambda$
• C. $\lambda /2$
• D. $\lambda /4$

Answer 1

The correct option is D $\lambda /4$

The wavelength of a wave is defined as twice the distance between 2 consecutive nodes and antinodes.

Now, the distance between an antinode and a node is 1/2 the distance between 2 consecutive nodes.

Therefore, $\lambda =2(2\times$ distance between a node and an antinode)

Hence, the required distance is $\lambda /4$
