The speed of electromagnetic waves in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second), which is denoted by the symbol 'c'. This speed is constant and represents the fastest speed at which energy or information can travel in the universe.
EM waves typically slow down when they travel through a medium compared to their speed in a vacuum. This decrease in speed is due to interactions with the atoms and molecules in the medium, which cause the EM waves to be absorbed and re-emitted resulting in a slower overall propagation speed.
EM waves are both Transverse and Longitudinal.
The speed is constant, at least for EM waves in a vacuum. The speed will still be approximately the same in other media, e.g. in glass. Different waves can have different frequences or wavelengths, but the speed will be the same.
Electromagnetic (EM) waves are self-propagating waves of electric and magnetic fields that travel through space at the speed of light. They do not require a medium to travel through, and can travel through a vacuum. EM waves are produced by the vibrations of charged particles and have both electric and magnetic components perpendicular to each other.
Electromagnetic waves can travel through a vacuum, while sound waves require a medium (such as air, water, or solids) to propagate. Additionally, electromagnetic waves can travel at the speed of light, while sound waves travel at a much slower speed.
No. The speed is THE SAME for all frequencies of electromagnetic waves.

No, not all electromagnetic waves travel at the same speed. The speed of an electromagnetic wave depends on the medium through which it is traveling. In a vacuum, all electromagnetic waves travel at the speed of light, which is approximately 299,792 kilometers per second.

Yes. They are all electromagnetic waves. They have the same speed in the vacuum. The speed of EM waves is about 300,000,000 meters/second. (The speed of EM waves is the ultimate speed that can be achieved by any object in the space. So for practical purpose this speed is taken as "Infinite speed". Your calculations about time and orientation change at this speed. When two things move in opposite direction with this speed, that is the "Ultimate speed" with which they can move apart. They will never be be able to see each other in that case, for example. Very few people could understood the theory of relativity by the great scientist, Albert Einstein.)
The disturbance that travels in a water and EM waves is sometimes known as electromagnetic radiation. Electromagnetic waves have the ability to travel through a vacuum.
Both being em wave they have the same velocity. And its value in vacuum is nearly 3 x 108 m/s
Gamma rays are a form of electromagnetic radiation, just as light is, and all EM waves propagate at the speed of light through a vacuum.
