Yes, they are.
They are electromagnetic.
No difference at all. Radio waves are one of many types of electromagnetic waves.
Infrared waves are shorter than radio waves and longer than visible light waves.
electromagnetic waves
Light and heat are very helpful to human beings, and radio has become pretty important too.
They are transverse waves.
No, an electromagnet is a device that produces a magnetic field when an electric current flows through it. Electromagnetic waves, on the other hand, are a form of energy that includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays, produced by the oscillation of electric and magnetic fields.
Frequency determines this.
Yes.
no, mechanical waves are not radio waves
to produce sound
Electromagnetic waves transfer energy through oscillating electric and magnetic fields. This transfer occurs through a vacuum because they do not require a medium for propagation. Examples of electromagnetic waves include light, radio waves, microwaves, and X-rays.
