Yes, it does.
Energy from the sun travels through the vacuum of space by radiation.
They use radio waves which are a type of electromagnetic waves. Electromagnetic waves can travel through a vacuum Ligth is a type of electromagnetic wave and that travels through space from the sun and the stars.
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
A microwave is near the "red" side of the electromagnetic scale. All electromagnetic travels at the same rate. Light is a form of electromagnetic radiation which travels through a vacuum (space). Thereofore, being a part of electormagnetic radiation, microwaves will travel through a vacuum.
In free space in a vacuum, EM energy travels at 300,000 km/sec
Radiation if that's the answer you're looking for... Radiation is the transfer of heat by electromagnetic waves (or light energy) traveling through space (but not outer space, just space like in the air).
299,792,458 meters per second in vacuum
Electromagnetic Wave
Yes, a vacuum is still a vacuum if electromagnetic waves are present. A vacuum is an area with no matter in it. We know that matter is anything which has mass and takes up space. Electromagnetic waves have no mass, and certianly take up no space. They're energy.
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. ... In electromagnetic radiation, its frequency is the number of electromagnetic waves moving past a point each second.
The sun produces energy via nuclear fusion. Electromagnetic energy in the form of light travels through the vacuum of space to reach earth via what we call radiation.
Light being electromagnetic wave is able to traverse right from Sun to the Earth through vacuum existing in between the two. This confirms electromagnetic wave can traverse through free space. Now free space itself is a medium but not a material medium.
