Visible light and ultraviolet (UV) light are both forms of electromagnetic radiation, and waves of each travel at the same speed. Human eyes are unable to see UV light because it is not in the visible range of the electromagnetic spectrum. If the frequency of one UV light wave is twice that of a visible light wave, how will their wavelengths compare?

The wavelength of the UV light wave will be half that of the visible light wave.

The wavelength of the UV light wave will be twice that of the visible light wave.

The wavelength of the UV light wave will be four times that of the visible light wave

A.The wavelength of the UV light wave will be the same as that of the visible light wave.
