Answer #1:
Very small wavelengths (near-infrared, far-infrared, sub-millimeter,
microwaves)are the types of electromagnetic waves that are harmful.
====================================
Answer #2:
You have to try really hard to be harmed by infrared, sub-millimeter,
or microwaves. In order to succeed with those, you have to arrange
somehow to put part of yourself in a place where the intensity of the
field is really high, such as sticking your hand under a broiler or into
a microwave oven while it's running, or looking into a transmitting
waveguide. In those cases, they can harm you in the same way that
a super-loud rock band can harm your hearing ... simply because
you've overloaded the structure of the human body, or of the materials
of which it's contructed.
The wavelengths that are intrinsically harmful are the ones with the
shortest wavelengths ... ultraviolet, X-rays, and gamma rays. Those
are the ones that can kill a cell, or tear a gene apart, with the shortest
exposure and at the lowest intensity.

Yes it is. It's the speed we call the "speed of light", although it applies equally to electromagnetic radiation at all frequencies/wavelengths.
Different types of electromagnetic waves have different frequencies; different wavelengths; and different energies per photon.
There are seven types of electromagnetic waves and they are: 1. Radio waves 2. Microwaves 3. Infra-red waves 4. (visible) Light waves 5. Ultra-violet waves 6. X-ray waves 7. Gamma rays
Only one type is produced: Electromagnetic radiation, distributed through the bands of wavelengths that we call light and heat.

The main difference between gamma rays and infrared rays is in their wavelengths. Gamma rays have the shortest wavelengths while infrared rays have longer wavelengths. Gamma and infrared rays are types of electromagnetic radiation.
One non harmful antigen type is blood types. These carry antigens that are not typically harmful to humans. The common blood types are: A, B, AB and O.

Whenever the electron falls from an excited state to a lower level, energy is released in the form of electromagnetic radiation. The Electromagnetic radiation can be light of different wavelengths and therefore different colors
Actually, there's only one. Even though we like to give different labels to electromagnetic waves with different wavelengths according to their uses or effects, they're all the same physical phenomenon.
Only one type is produced: Electromagnetic radiation, distributed through the bands of wavelengths that we call light and heat.
Ozone layer absorbs the harmful UV rays. It acts as a shield to the earth.
Electormagnetic (EM) waves are all the waves and subsequent wavelengths that make up the Electromagnetic Spectrum. This includes but is not limited to: Radio Waves Infered Waves Visible Light Micro Waves X- Rays If you want a complete list look up the Electromagnetic Spectrum.
