Stationary waves are set up on a rope of length 1.0 m fixed at both ends - AQA - A-Level Physics - Question 18 - 2020 - Paper 1

In even-numbered harmonics, the midpoint is indeed a node where there is no displacement, making this statement correct.

The wavelengths for standing waves on a rope fixed at both ends can be calculated using the formula $\lambda_n = \frac{2L}{n}$, where $n$ is the harmonic number. For $n = 5$, the wavelength is $\lambda_5 = \frac{2 \times 1.0}{5} = 0.4$ m. This statement is correct.

For the fifth harmonic, there are a total of 6 nodes (at each end and at 5 evenly spaced points along the length of the rope). Therefore, this statement is not correct.
