Hey, I have heard that red light travels shorter than regular light. I am thinking of flashlights, where I learned that people in the army uses red light to make them less visible. Is this true?
The atmosphere scatters blue light more than red light. At sunrise and sunset, you see the light coming toward you with much of its blue component scattered away.Bob S said:Why does the sun look reddish at sunrise and sunset?
Red light can travel through a vacuum indefinitely, but it will eventually dissipate or scatter when it encounters an object or medium that absorbs or reflects it.
Yes, all colors of light, including red light, travel at the same speed in a vacuum, which is approximately 299,792,458 meters per second.
It depends on the material and thickness of the object. Some materials, such as glass, allow red light to pass through, while others, like metals, absorb or reflect it. Thicker objects will also absorb more red light than thinner ones.
Red light can travel through water, but it will be absorbed or scattered over a shorter distance compared to in a vacuum. The exact distance depends on the clarity and depth of the water, as well as any impurities or particles in the water that can scatter the light.
Yes, red light can travel through the Earth's atmosphere, but some of it will be absorbed or scattered by gases and particles in the air. This is why the sky appears blue during the day, as blue light is scattered more than red light. However, red light is able to pass through the atmosphere and reach our eyes, which is why we can see red objects in the distance.
