Not including the endpoints, there are 3 nodes.

What is a node?

In a wave, a node is a stationary point. For example in a vibrating string of a guitar, the endpoints would be nodes.

But here we need to ignore the endpoints, we only know that the wave has two wavelengths.

For a wave with N wavelengths the number of nodes that are not endpoints is just given by 2*N - 1  (while if we counted the endpoints we would have 2*N + 1).

So in this case we have N = 2, then there are 2*2 - 1 = 3 nodes.
