Final answer:
The limits of the visible spectrum are arbitrarily defined. The statement is True.
Step-by-step explanation:
The statement is True. The limits of the visible spectrum are arbitrarily defined. The visible spectrum is the narrow region of the electromagnetic spectrum with wavelengths between about 400 and 700 nm, which corresponds to the range of colors that humans can perceive.
The boundaries of the visible spectrum can vary depending on the context and the observer. For example, some people may have a wider or narrower range of colors they can perceive, and certain animals can see beyond the human visible spectrum, either into the ultraviolet or infrared range.
When it comes to light detection, true is the statement that light signals can pass through a vacuum into the eye, allowing us to see objects in space such as stars and planets.
