Visible light is part of the electromagnetic spectrum and 10,000 times bigger than the radio spectrum, affording potentially unlimited capacity.

可见光是电磁光谱的一部分，比无线电频谱要大1万倍，因而可说具有无限的开发潜力。

Ultra-violet light is not in the part of the visible spectrum, but why does an ultra-violet lamp emit violet colored light?

紫外光系?湛杉?馄滓酝?但系点解我地可以见到紫外光灯发出紫色???。

We can plug this in further when we're talking about the visible part of the light spectrum, because we know that for n final equals 2, then that would mean we plug in 2 squared here, so what we get is 1 over 4.

当我们讨论可见光谱的时候,我们可以把这个代进去,因为我们知道n末是等于2的,这意味着我们可以。

But crystal fibres push the range of single-mode wavelengths right into the visible part of the spectrum, opening up huge new tracts of wavelength for telecommunications.

This part of the infra-red spectrum, with wavelengths close to that of visible light, carries heat energy.

Edison bulbs function by making a Tungsten filament very hot, and a hot object glows: radiating energy on a broad spectrum of wavelengths, only a small part of which is visible to the eye.
