Answer 2

Since light travels at its fastest in vacuum, the maximum speed of light will be our necessary answer.

Explanation:

• Visible light is the light that can be seen by humans. Multiple kinds of light that are not visible to humans can be observed by other creatures, according to scientists.
• The true reason is that we have no idea what light is, and no one knows what light is, so we're creating a map of what light might be, and if that's how we imagine light, we'll be able to make better predictions.
• Therefore, the speed of light is 3×$10^{8}$ m/s
