Electromagnetic waves
Unlike mechanical waves, these waves can travel though vacuum because they do not need a medium of travel.
Explanation:
This is how sunlight reaches earth. Sunlight has many wavelengths if electromagnetic waves called an electromagnetic spectrum. The electromagnetic spectrum ranges from the high energy waves called gamma rays (they have the shortest wavelength and highest frequency). On the other end of the spectrum are the lowest energy waves called radio waves (they have the longest wavelength and lowest frequency).
