Audent is trying to answer the question How are electromagnetle and mechanical waves different? Does this data above help answer that question?
O A Yes, it shows that mechanical waves can travel without a medium and electromagnetic waves must have a medium.
OB Yes, it shows that electromagnetic waves move slower when going from ases to liquidato solids, but mechanical waves move faster
OO No, both waves changed speeds with different materials and electromagnetic waves shouldn't change speed as their speed is a constant.
OD. No, the wave speed data does not support a valid difference between electromagnetic and mechanical waves
