Based on the diagram, which of these conclusions is correct about the two waves?
They have equal frequencies.
They have equal wavelengths.
The amplitude of Wave 2 is double the amplitude of Wave 1.
The frequency of Wave 2 is double the frequency of Wave 1.
At first glance, the amplitudes are the same (height of the waves). It can be seen that Wave 2 goes up and down twice as much in one second as Wave 1. then, wave 2 has half the period and "twice as much as wave 1".
