They are equal.
If both speeds are measured in the same medium, whether it be vacuum, water, or jello, then they are equal.
They are the same.
If both of them are in the same substance, then their speeds are equal.
Same speed - light and gamma rays are both electromagnetic waves, but with different frequencies.
About 2/3 its speed in a vacuum.
They are both forms of electromagnetic radiation and, in a vacuum, would travel at the same speed.
If both speeds are measured in the same medium, whether it be vacuum, water, or jello, then they are equal.
They are the same.
If both of them are in the same substance, then their speeds are equal.
vacuum is measured in pressure. To get a vacuum you need a negative pressure. that would be inches of mercury hg
light in a vacuum
Visible light and gamma rays are different parts of the full spectrum of light. Since they are really both just light, they travel at the same speed, the speed of light. 186,000 miles per second.
A klystron, magnetron or travelling-wave tube will generate microwaves. So will a vircator and an inductive output tube. These are just some of the vacuum tubes used to generate microwaves. In a microwave oven, the magnetron, which is a type of cavity resonator, is the device of choice.
A vacuum is not visible, as it is an absence of matter. Matter must exist to be seen, and so a vacuum cannot be seen.
Same speed - light and gamma rays are both electromagnetic waves, but with different frequencies.
All electromagnetic waves move at the same speed, at least in vacuum. X-rays and microwaves ... as well as radio, infrared, ultraviolet, heat, and visible light ... are all electromagnetic waves, and travel at the same speed.
Both radio waves and tv waves are electromagnetic waves. So both have the same speed in vacuum. Of course radio waves are of lower frequency compared to that of tv waves.
