Problem set 6 question 11

** **

I get the general gist of this problem, but I don't understand the difference between the first two sub questions:

What would be the frequency of your SHM if the wave, with nodes at both ends, contained exactly two antinodes?

Answer the same question for a wave consisting of two antinodes.

Both seem to ask for two antinodes, but the solutions are different. How do we infer that in the first one we have two nodes and in the second we have three?

@&

This question should read

'Answer the same question for a wave consisting of three antinodes.'

Thanks for pointing this out. I was unaware of the typo.
