Which type of wave is an electromagnetic wave?
- Longitudinal wave
- Mechanical wave
- Transverse wave (correct)
- Sound wave
Can an electromagnetic wave travel through empty space?
Can an electromagnetic wave travel through empty space?
- It depends on the wave frequency
- No, because it needs matter to travel through
- It depends on the wave amplitude
- Yes, because it travels through an EM field (correct)
Do electromagnetic waves get weaker as they travel through space?
Do electromagnetic waves get weaker as they travel through space?
- No, because no energy is lost (correct)
- Yes, because they lose energy to matter
- It depends on the wave frequency
- It depends on the wave amplitude
