Question

what is visible light and how does it travel?

Explanation:

Visible light is a part of the electromagnetic spectrum. It is the range of wavelengths that the human eye can detect. Light travels in straight lines as rays. It can also be described as traveling in waves. In a vacuum, light travels at a constant speed of approximately \(3\times10^{8}\) meters per second.

Answer:

Visible light is the part of the electromagnetic spectrum detectable by the human eye. It travels in straight lines (as rays) and also as waves, at a speed of about \(3\times10^{8}\) m/s in a vacuum.
