Electro magnetic force?
It's the force that is brought by a magnetic field. The Sun uses electro-magnetic waves to provide solar radiation to us because it can travel through a vacuum.
What waves are unique because of there ability to travel through a vacuum. a space that contains no particles of matter?
"electro-magnetic"
What can travel in a vacuum?
Light or radioactive particles. They uses electro magnetic radiation as a medium for them to travel through, Waves like sound can not travel through vacuum because they need physical mediums like air.
Which distinguishes electromagntic waves from mechanical waves?
Electro magnetic waves can pass through medium of free space ie vacuum but mechanical waves cannot do so. Mechanical waves such as sound definitely needs a material medium air, water etc. But light being electro magnetic could pass through even vacuum. Actually in between the sun and earth there is vacuum. Yet we receive light right from Sun towards earth.
In a vacuum do different parts of the electromagnetic spectrum travel at the same or different speeds?
In vacuum, every imaginable wavelength of electromagnetic radiation, from longer than radio waves to shorter than gamma rays, travels at 299,792,458 meters per second.

Wwhat speed do gamma rays travel at?
Like all forms of light (ie, electro-magnetic radiation), gamma rays in a vacuum travel at exactly 299,792,458 meters per second.
Can magnetic fields travel in vacuum?
Yes
Do x-rays go through vacuum?
Yes, easily. All types of electro-magnetic radiation - light, radio, radar, x-ray etc - pass very easily through vacuum.

Diffrene between electro magnetic and mechanical waves?
An electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum. They are caused due to varying electric and magnetic fields. Radio waves and light waves are examples for elect..These are waves that can pass through vacuum in addition to passing through matter. In other words, a material medium is not necessary for their propagation. They consist of periodic variations of electric and magnetic fields at right angles to each other and also at right angles
Can macnetic waves travel at the speed of ligth?
Light is an electromagnetic wave. Electromagnetic waves travel at the speed of light. Electric and magnetic waves don't travel on their own - the wave travels as a combined electric and magnetic wave.
Does light waves travel fastest through empty space?
Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.
What is the highest possible velocity of electromagnetic phenomena and light?
All electro magnetic radiation (including radio waves and visible light) travels at the speed of light or 300,000 km/sec
