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.

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.
8 minutes
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.
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.
The wavelength is too long to be seen by our eyes.
Long wavelength visible light would appear more towards the red end of the spectrum, closer to infrared light. This type of light is characterized by lower energy and longer wavelengths, making it less energetic but still visible to the human eye.
