Give one example of a transverse wave that can travel through a vacuum.
How to approach this question
Recall the types of waves in the electromagnetic spectrum. All of these are transverse waves and can travel through a vacuum. Name any one of them.
Full Answer
Light
Transverse waves that can travel through a vacuum are called electromagnetic waves. The electromagnetic spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Any of these would be a correct answer.
Common mistakes
✗ Giving an example of a mechanical wave, like sound or water waves, which require a medium to travel.\n✗ Giving a general answer like "electromagnetic wave" when a specific example is asked for (though this may be accepted).
