A 2-column table with 3 rows. The first column labeled mechanical waves has entries ocean water, light waves, earthquake waves. The second column labeled electromagnetic waves has entries sound waves, radiation waves, X-ray waves. How should the table be changed to correctly distinguish between mechanical and electromagnetic waves? Earthquake waves and radiation waves need to change places. Light waves and X-ray waves need to change places. Ocean waves and X-ray waves need to change places. Sound waves and light waves need to change places.
