Question

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

Answer 1

Answer:

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.
