The wavelength of infrared light is too long for humans to see.
if it was infrared light, which is basically heat, it would take about 10 mins. normal light would take about 8 mins at most.
The wavelength of infra-red light is LONGER than the wavelength of red light, and longer than anything to which the eye responds.
Infrared waves are used in fiber optics because they have a longer wavelength, allowing them to travel further distances without losing signal strength. Additionally, infrared waves are less susceptible to interference from external light sources, making them ideal for transmitting data over long distances in fiber optic cables.

Traveling 39 light years would take 39 years at the speed of light.
Traveling 40 light years would take 40 years 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.
The wavelength is too long to be seen by our eyes.
It would take approximately 65 years to travel at the speed of light from Earth to Aldebaran, which is about 65 light-years away. However, currently, we do not have the technology to travel at the speed of light.
In an optical fiber, the speed of light is determined by the refractive index of the medium. Light travels faster in a medium with a lower refractive index. Typically, the refractive index of a material decreases as the wavelength of light increases. Since ultraviolet light has a shorter wavelength than infrared light, it generally travels faster in an optical fiber.
