Aboat at rest on the ocean moves up and down as water waves pass beneath it. what can be concluded about the nature of the water particles in the waves from this observation?

Water particles move up and down while the waves passes.

The wave carries the energy forward. The medium particles (here, water particles) do not move along with the wave they oscillate about a fixed position.

As the boat at rest moves up and down, it means the water particles are oscillating vertically up and down while the wave is carrying the energy forward.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

b.

hope this : )
