Which light travels faster in an optical fiber - ultraviolet or infrared?
Neither. All electromagnetic radiation (light) travels at a constant speed through whatever medium it encounters. Light in a vacuum, for instance, is about 186,282 miles per second; whereas in a fiber optic cable it chugs along at only 115,000 miles per second.*What distinguishes ultraviolet from infrared is the amount of energy associated with it, reflected in its frequency. Assuming that a particular cable is transparent to both forms of radiation (which may or may not actually be the case, as another name for infrared radiation is heat) it is likely that the ultraviolet energy would travel farther before its signal would need to be reboosted.*The speed of light through a medium is proportional to its index of refraction. The index of refraction of fiber optic cable is about 1.62; this means that light travels through it only about 60% as fast as it does through outer space.
How long does the Sun Energy's take to get to Earth?
if it was infrared light, which is basically heat, it would take about 10 mins. normal light would take about 8 mins at most.
Difference between infrared waves and red light waves?
Infrared waves have longer wavelengths compared to red light waves. The wavelengths of infrared waves are too long for the naked eye to see, while red light waves can be seen as part of visible light.
How long would it take to travel at the speed of light from Earth to Aldebaran?
It would take 65 years 11 months to travel to Aldebaran from Earth traversing at the speed of light.
How long would it take for light to travel 14 billion light years?
14 Billion years
How long would it take to travel by light speed to get to the sun?
8 minutes
Is the infrared light too long or short?
how is named after the hubble space telescope
How long would it take to get to the sun if you could travel at the speed of light?
Sunlight takes 8.4 minutes to travel 93 million miles to Earth. It would take us that long to reach the Sun at light speed.
How is infrared radiation different from visible radiation?
Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).
How long would it take to travel 4 000 light years?
Like any distance, it depends on how fast you are going. At the speed of light it would take 4,000 years to travel that distance.
How long is 28 lightyears?
A lightyear is not a measure of time but a measure of length that light can travel in 1 year. It would take 28 years for light to travel a lightyear
How long would it take light to traver around the world?
Light can travel once around the earth in .00013358 seconds.
