Which of these lists is arranged in order from smallest wavelength to longest wavelength?

a. seiches, tsunami, wind waves, tides.
b. wind waves, seiches, tsunami, tides.
c. wind waves, tsunami, seiches, tides.
d. tides, seiches, tsunami, wind waves.
e. wind waves, tides, tsunami, seiches.

b. wind waves, seiches, tsunami, tides.

Explanation:

The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave.  Usually, the bigger the wave, the greater the wavelength.

wind waves: small waves caused by the wind.  These waves tend to be small and with a short wavelength.

seiches: are usually waves on a lake or other closed water bassin.  They can be pretty high from a human perspective, so they are definitely bigger than wind waves.

tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.

tides: yes, a tide can be considered as a huge wave... that's running throughout the planet.  We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.
