• crest

• trough

• amplitude

• wavelength

Multiple Select

Which of the following statements about wavelength are correct?

• Wavelength is the distance from one crest to the next crest

• Wavelength can be measured from trough to trough

• Longer wavelengths mean waves are closer together

• Water particles move only at the surface

Multiple Select

Which of the following are true about shallow water wave orbitals?

• Orbitals become flattened ellipses

• Bottom friction affects the orbital motion

• Water particles make complete circles

• Shallow water means depth is less than half the wavelength
