one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to asa)day light. b)white light. c)shortwave radiation. d)ultraviolet radiation.

b) White light

Also known as visible light consist of a spectrum of different waves. Technically, white is not a color or a wavelength characterized by a white color. Rather, White light is a combination of many colors of the visible spectrum. It shows the full spectrum of electromagnetic spectrum.

Wavelengths of the "visible spectrum" combine to form what we refer to as the white light.

Explanation:

When the spectrum of the visible light combine, they form a colorless light. This colorless light is referred to as 'white light'. The 'white light' is actually a fusion of all the "wavelengths" in the "visible spectrum" of the whole electromagnetic spectrum. The light appears white because the wavelengths that make this light are blended in such a manner that they need to be split with a prismatic device to observe the light bands.
