Nothing, apart from the fact that your eyes are only capable of seing "visible light" , ie within a certain wavelegth (couple hundred nanometres). All electromagneic waves are the same, save their wavelengths which range from gamma rays (shortest) to radio waves (longest, couple metres long). However, waves above Microwaves (X-rays, gamma rays) contain enough energy per photon to ionize electrons (remove them from their atoms). This can cause chemical bonds to break, which is why X-ray and gamma ray radiation can be dangerous.
Light is ONE SMALL RANGE of the electromagnetic spectrum. In other words, electromagnetic waves within a relatively small range of frequencies - the frequencies that we are adapted to seeing with our eyes - is called "visible light", or simply "light".
Mechanical waves require a medium to travel, where electromagnetic waves do not.
light waves are electromagnetic
Visible light and radio waves are both two types of the same radiation (electromagnetic waves). The difference is that visible light has a higher frequency; a higher energy per photon; and a smaller wavelength.
they dont send out magnetic signals

Light is an electromagnetic wave.
Mechanical waves require a medium to travel, where electromagnetic waves do not.
light waves are electromagnetic
The type of waves that are electromagnetic are the visible light waves
Light is the visible form of electromagnetic waves.
Electromagnetic waves are generated through frequency oscillations which usually involve a coil of wire or in an extension such as a transmitting antenna. Lasers are light, formed in a coherent beam and generally don't exhibit electromagnetic waves.
Visible light and radio waves are both two types of the same radiation (electromagnetic waves). The difference is that visible light has a higher frequency; a higher energy per photon; and a smaller wavelength.
Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
they dont send out magnetic signals
Terahertz and infrared radiation.
Transverse / Electromagnetic depending on the context of the question
