Answer 1

The correct completion of the comparison is: The difference in the second wave, shown by the red line, is its longer wavelength. Both waves have the same amplitude.

The correct completion of the comparison is:

The difference in the second wave, shown by the red line, is its longer wavelength. Both waves have the same amplitude.

Wavelength is the distance from one crest of a wave to the next. Amplitude is the distance from the middle of the wave to the crest.

The two waves in the diagram have the same amplitude, but the second wave has a longer wavelength. This means that the second wave has fewer crests and troughs per unit distance.

Here is a table attached below summarizing the comparison of the two waves.
