If both of them are in the same substance, then their speeds are equal.
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.
Same speed - light and gamma rays are both electromagnetic waves, but with different frequencies.
About 2/3 its speed in a vacuum.
No. Their speeds are identical.
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.
Radio waves and light are the same exact physical phenomenon, and differ only in their wavelength (frequency). Their speeds are identical.
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.
Same speed - light and gamma rays are both electromagnetic waves, but with different frequencies.
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.
at cruising speeds you will be in a high vacuum situation that advances the timing for better economy.
Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger. However, sound has very different speeds, depending on the medium in which it travels.Assuming you mean the speed of sound in air, the speed of light (in a vacuum) is about 800,000 times larger.

Not in a complete vacuum, you need some molecules present to be stimulated
About 2/3 its speed in a vacuum.
