Answer:
Vacuum
Step-by-step explanation:
Concept being tested: Waves and types of waves
To answer the question we need to define both electromagnetic waves and mechanical waves.
- Waves can be classified as either electromagnetic waves and mechanical waves based on whether they require a material medium for transmission or not.
- Electromagnetic waves do not require a material medium for transmission and can travel through a vacuum.
- Mechanical waves, on the other hand, are waves that require a material medium for transmission.
What are examples of electromagnetic waves and mechanical waves?
- Examples of electromagnetic waves include gamma rays, radio waves, visible light, etc.
- Examples of mechanical waves include sound waves and water waves.
Therefore, the answer to our question is;
- Electromagnetic waves are not mechanical waves, which means they can travel in a vacuum.
