there is no such thing as dark, only the absence of light.
No. All colors travel at the same speed. It is called "the speed of light".
No, light in a medium will travel at a slower speed.
No, light does not always travel at the same speed in all mediums. Its speed can vary depending on the medium it is passing through.
All electromagnetic waves travel at the speed of light in a vacuum and can be characterized by their wavelength and frequency.
No, both light in air and radiation from a microwave oven travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second. Therefore, they both travel at the same speed.
Both infrared and microwave light travel at the speed of light in a vacuum, which is about 299,792 kilometers per second. Therefore, they both travel at the same speed.
They don't really travel at the same speed, but, on television, the distance they travel is so short, that the difference between the speed of sound and the speed of light is almost non-existant.
Both visible light and gamma rays travel at the speed of light in a vacuum, which is approximately 299,792 kilometers per second (or about 186,282 miles per second). Thus, there is no difference in the speed at which visible light and gamma rays travel.
All colors of light travel with the same speed.
All electromagnetic waves travel at the same speed in vacuum.
'Radio' waves are physically and electrically identical to light waves except for their frequency (wavelength), and they travel at the same speed as light does.
Yes, gamma rays travel at the speed of light, which is approximately 299,792 kilometers per second in a vacuum. This is because gamma rays are a form of electromagnetic radiation, like visible light and radio waves, and all forms of electromagnetic radiation travel at the speed of light in a vacuum.
