The relationship between frequency and wavelength is inverse (opposite). When one goes up, the other goes down. This is described by the formula \( v = f \lambda \), where \( v \) is the speed of the wave, \( f \) is the frequency, and \( \lambda \) is the wavelength.
Regarding the second question, without the graph, I cannot determine the correct answer regarding frequency and amplitude. If you can provide more information or describe the graph, I'd be happy to help!
