The electromagnetic spectrum includes all wavelengths from radio waves up to gamma rays. The visible light is just a small portion of the electromagnetic spectrum positioned between infrared rays and ultaviolet.

The electromagnetic spectrum is a range of the all electromagnetic waves, starting from the highest energy and frequency wave: the gamma rays, and followed by X rays, UV radiations, visible light, infrared radiations, microwaves and radiowaves. Visible light is a very narrow segment of the whole electromagnetic spectrum (with a wavelength range of 380 - 780 nanometer) , the only electromagnetic wave that human can perceive.

The visible Light is infact a part of the EM spectrum.
The EM spectrum is in fact a band of radiations of various frequencies having different wavelengths.
The gamma radiations have the maximum frequency and the minimum wavelength and top the EM spectrum. The visible light having a freq. of 8x10^14 to 4x 10^14, is next to the UV and preceed the infra red waves.
The spectrum may summarised as:
Gamma Rays, Xrays, UV rays, Visible Light (Violet, Indigo, Blue, Green, Yellow, Orange, Red), Infra red, Heat Radiations, Micro waves, Ultra high Freq, Very high radio frq., radio freq., Power Freq.

"The electromagnetic spectrum is the distribution of electromagnetic radiation according to energy (or equivalently, by virtue of the relations in the previous section, according to frequency or wavelength). "
"The electromagnetic spectrum is the range of all possible electromagnetic radiation. Also, the "electromagnetic spectrum" (usually just spectrum) of an object is the range of electromagnetic radiation that it emits, reflects, or transmits."

the electromagnetic spectrum includes all forms of light, while visible light is only a tiny fraction that humans can see. the elecrtomagnetic spectrum includes microwaves, uv rays, radio waves, infrared, "soft" x-rays, "hard" x-rays, gamma rays, and visible light.

Visible light is in the electormagnetic spectrum... just a defined region.
