The speed of light varies because the absolute speed of light "C" is measured in a vacuum. When light travels through air, it goes slightly slower. When light travels through denser mediums still, such as glass, the speed decreases further still.
No. The speeds of convection and conduction vary, but they are nowhere near the speed of light.
The speed of light. (It doesn't vary depending on altitude, or any other factor.)
Speed of light doesn't travel. Light travels.The speed of light doesn't vary depending on the planet; it may, however, vary depending what it goes through. For example, the speed of light in a vacuum is 300,000 km/second; the speed of light in glass is about 2/3 of that value.
Obstructions, black holes, etc.
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.
The speed of light of different colors passing through the same medium remains the same. This is because the speed of light in a medium is constant and does not change based on the color of the light.
basicly the answer is that light speed does not vary due to weather. This is a difficult subject to understand I really recommend the wikipedia light speed article. Go below for the link
The speed of an electron in motion can vary, but typically ranges from about 1 to 10 of the speed of light, which is approximately 186,282 miles per second.
No, the speed of sound is much slower than the speed of light. The speed of sound in air is around 343 meters per second, while the speed of light in a vacuum is approximately 299,792,458 meters per second.
False. Newton's work did not involve the speed of light and sound. The concept of constant speed of light was later formulated by Einstein in his theory of relativity. The speed of sound can vary depending on the medium it travels through.
No, light does not travel at the same speed through all transparent media. The speed of light can vary depending on the medium it is traveling through. It typically travels slower through materials like glass or water compared to its speed in a vacuum.
All photons travel at the same speed in a vacuum, which is the speed of light, but their velocities can vary when passing through different mediums.
