electromagnetic waves are waves that do not require a medium to move. these waves can be microwave waves, ultraviolet rays, and also light waves. we can see colors because of electromagnetic waves.

How is electromagnetic radiation used ?
They travel at different speeds.
Electromagnetic waves are transverse in nature where as sound waves are longitudinal. Electromagnetic waves can pass even through vacuum but sound waves are mechanical waves that means it needs badly a material medium Sound waves can be sensed by ear where as electromagnetic waves are sensed by eyes.
need to describe in five ways how electronic waves differ each other
There are many ways of classifying waves. One of those ways are by categorizing them by their ability or inability to transmit energy through a vacuum. The two categories are electromagnetic waves and mechanical waves. Light is an electromagnetic wave, which has the ability to travel through a vacuum (empty space). Sound is a mechanical wave, it needs to travel through a medium (air, water, etc.) However, if you're looking for waves categorized by their wave length, they are (Going from shortest wavelength to longest.. Keep in mind, the shorter the wave length, the more energy it has): a) Gamma Rays b) X-Rays c) Ultra Violet Rays d) Visible Light e) Infrared f) Microwaves g) Radio Waves (p.s. These are electromagnetic waves)
two ways of radiation are the sun because its heat travels in electromagnetic waves and radiates the earth and an electric radiator because it heat will radiate whatever it is heating just like the sun will

Electromagnetic waves are very much different from the matter waves and in many ways. a) Speed of matter waves is very much less than the speed of electromagnetic waves. b) Matter waves cannot be radiated in empty space unlike electromagnetic waves. c) Matter waves are just associated with the particle, not emitted by it Matter waves have smaller wave lengths than electromagnetic waves
In frequency or wavelength.

they both have wavelenghth and have energy
Electromagnetic waves, such as infrared and visible light
micro waves can be used in:ovens to cook food.are also used for satellite communicationand mobile phones.satellite TV
No, compressional waves travel through liquids and gases. Transverse waves pass through solids. You may also be forgetting electromagnetic waves such as light, radio, x-rays, etc that propagate in neither of these ways and can even pass through vacuums.
Electromagnetic radiation (EMR) is strange. It is like waves in some ways, and it is like particles in some ways. EMR includes all light and radio waves, and other categories as well. One of the properties of EMR is that it does not need a 'medium' to move through. It can easily travel through vacuum. Other kinds of wave need a physical medium through which to propagate. So EMR of a wide range of frequencies is coming toward us from all points of the sky, traveling through the vacuum of space until it is absorbed by particles in space, in our atmosphere, or at the surface.
