Answer:
A. electromagnetic waves only
Explanation:
brainliest please? :))
a) Electromagnetic waves only can travel through space
Electromagnetic waves are the waves that are propagated by simultaneous period variation of electric and magnetic filed intensity .
Longitudinal wave and mechanical wave require a particular medium to travel , and in vacuum their is no medium that helps the waves to propagate because their is no particle present in vacuum . Hence , their is absence of any matter , wave cannot travel through it .
Because electromagnetic waves do not need molecule to travel and electromagnetic wave are transverse waves and they have oscillating magnetic and electric field thus do not need a medium to travel .
hence , correct option a) Electromagnetic waves only
