Current Question (ID: 16005)

Question:
$\text{Stationary waves are formed on a stretched string. If the wavelength is } \lambda, \text{ then the distance between two points having the maximum displacement can be:}$
Options:
  • 1. $\frac{3\lambda}{2}$
  • 2. $4\lambda$
  • 3. $\frac{5\lambda}{2}$
  • 4. $\text{All of these}$
Solution:
$\text{Hint: Distance between 2 consecutive nodes or antinodes } = \frac{\lambda}{2}$ $\text{Step: Find the distance between two antinodes.}$ $\text{So, the distance between two points having maximum displacement } = n \times \frac{\lambda}{2}$ $\text{distance between 2 consecutive antinodes } = \frac{n\lambda}{2}$ $\text{Hence, option (4) is the correct answer.}$
