Which statement is true for electromagnetic and mechanical waves? (1 point) Electromagnetic waves travel mainly through matter, and mechanical waves travel only through a vacuum. Mechanical waves require a medium to travel through, but electromagnetic waves do not need a medium. Mechanical waves sometimes travel through a vacuum, and electromagnetic waves sometimes travel through matter. Electromagnetic waves require a medium to travel, but mechanical waves do not need a medium.

Mechanical waves require a medium to travel through, such as air, water, or solid materials. This means that sound waves, for example, can't travel in space where there's no air. In contrast, electromagnetic waves, like light and radio waves, can travel through a vacuum, as they propagate through oscillating electric and magnetic fields, allowing them to travel across the vast emptiness of space! When thinking about real-world applications, consider how these waves are tapped into for communication. We rely on mechanical waves for sound when we talk on the phone or listen to music, while electromagnetic waves transmit signals to our televisions and radios. This fascinating combination allows us to connect and interact with the world in myriad ways, from experiencing our favorite tunes to enjoying a movie night at home!
