A string is fixed at both ends and vibrates in its third harmonic. How many nodes and antinodes are present in this standing wave?

The distance between two consecutive antinodes of a standing wave on a stretched string is $0.40 \text{ m}$. What is the wavelength of the travelling waves that produce this standing wave?

A pipe of length $L$ is closed at one end and open at the other. A standing wave is established at the fundamental frequency. The fundamental wavelength is $\lambda = 4L$. Which row correctly identifies the displacement boundary conditions at each end?

A string of length $1.2\text{ m}$ is fixed at both ends and vibrates in its second harmonic. What is the distance between a node and its nearest antinode?
