Electromagnetic waves do not require a medium to travel (light, radio).
Light, as a electromagnetic wave has both magnetic and electrical components.
The scientific study of physics is composed of many areas including looking at light. The two components of a light wave are electrical and magnetic.
the distance between two consecutive compressions or rarefactions of a light wave is called its wavelength.
Frequency or wave length.The relation between frequency f and wave length lof a light waveis given by; f = c/l, where c is light's speed.
Just ONE property, the wavelength of the light. The colour of visible light depends on its wavelength. These wavelengths range from 700 nm at the red end of the spectrum to 400 nm at the violet end.

You seem to be talking about a light wave. If you increase the amplitude the light gets brighter, and if you decrease it gets dimmer. Amplitude has no effect on colour.
The electric and the magnetic field components.
the answer is: magnetic...magnetic and electrical
Light is known as electromagnetic radiation because it has two complementary components which were found to be a magnetic field wave in synchronous motion with an electric field wave.

Polarization and Interference confirm light is a wave.
the two things that determine the color of a light wave are its wavelength and the material it reflects from.
Light has two natures that can be thought of as both a wave and a particle.
A particle & a wave
That is called an electromagnetic wave. Electromagnetic waves include visible light, infrared, ultraviolet, x-rays, gamma rays, and radio waves. If both the electric and the magnetic components are standstill (do not move) there will be no propagating waves. The wave will be created if either the electric or the magnetic moves or disturbed. The electromagnetic wave will spread out everywhere on the plane with a frequency perpendicular to its direction. In vacuum, the wave travels at the speed of light. In other mediums, the speed will be less than the speed of light. The wave will spread out uniformly an all direction if the density if the medium in uniform.
