Waves 1 and 2 show two different sound waves. look carefully at the two waves.

in what ways do their wave characteristics differ?

a) wave 1 has a longer wavelength and a higher amplitude than wave 2.
b) wave 1 has a shorter wavelength and higher amplitude than wave 2.
c) wave 1 has a longer wavelength and lower amplitude than wave 2.
d) wave 1 has a shorter wavelength and a lower amplitude than wave 2.

I believe the correct answer is A, Wave 1 has a longer wavelength and a higher amplitude than wave 2. Both A and B are transverse wave, therefore, the wavelength is the distance between two successful crest (highest point) or two successful trough (lowest point). In this case, wave 1 has a longer wavelength than wave 2. Amplitude is the maximum displacement of particles in a wave on either side from the equilibrium point. From the diagram wave 1 as a higher amplitude compared to wave 2.
