Is it possible for an electromagnetic wave to travel through a vacuum?
Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
What type of electromagnetic wave travels fastest in a vacuum?
Electromagnetic waves (and therefore radio waves) travel about one million times faster than sound waves. 5) Radio waves and light (i.e. visible light) are both electromagnetic waves and travel at the same speed through a vacuum. Radio waves have a longer wavelength and a smaller frequency than visible light.
Can microwaves travel through a vacuum?
Microwaves are part of the electromagnetic spectrum, like light, x-rays, radio waves… All electromagnetic waves can pass through a vacuum, including microwaves.
