Model answer
What a good answer should say
- Electromagnetic waves are characterized by their ability to travel through a vacuum and have a wide range of frequencies, while mechanical waves require a medium and are limited to the properties of that medium.
- The most significant distinction is that electromagnetic waves can propagate without a medium, making them essential for technologies like wireless communication.
- Mechanical waves are applicable in scenarios such as sound transmission and water waves, where a medium is present.
