Radiant energy, the energy carried by electromagnetic waves, can be transmitted through any number of media, including visible light, gamma rays, radio waves, x-rays, infrared waves and ultraviolet waves. The energy emitted from the sun is an example of thermal radiation, which is also a type of radiant energy.Know More
Radiant energy is transmitted through all of the different types of electromagnetic waves. These waves range from radio waves, which have the lowest frequency and longest wavelength, to gamma rays, which have the highest frequency and shortest wavelength. Radiant energy is carried by massless electromagnetic particles called photons. Quantum field theory unites the seemingly paradoxical concept that electromagnetic radiation, and thus radiant energy, can be carried by both particles and waves simultaneously.
When electromagnetic waves and radiant energy come into contact with an object, they are absorbed and become heat. Radiant energy from the sun generally enters the Earth's atmosphere as high frequency waves, striking the earth's surface and heating the planet. The nuclear fusion reaction of the sun creates its radiant energy.
Radiant energy is used by people to produce radiant heat. Energy is obtained and used for heating water, either from sunlight or infrared lamp technology. Radiant energy heats objects, rather than the air, and is thus different from more conventional heating methods.Learn more about Particle Physics
According to the Encyclopedia Britannica, in terms of classical theory, electromagnetic radiation refers to energy that flows at the universal speed of light via free space or a material medium in the form of electric and magnetic fields that comprise electromagnetic waves, such as radio waves, gamma rays and visible light. Electromagnetic waves are characterized by their intensity and the frequency of the electric and magnetic field's time variation.Full Answer >
There are two types of sound waves: transverse and longitudinal. Each wave has its own shape and specific materials that they can conduct through.Full Answer >
According to Pelamis Wave Power, wave energy is energy transferred from wind forces to the waves of a body of water, such as the ocean. Wave energy should not be confused with tidal energy.Full Answer >
Electromagnetic and mechanical waves differ in that electromagnetic waves are always longitudinal and do not require a known medium, while mechanical waves are either longitudinal or compression waves and require a medium. All known electromagnetic waves are also known as forms of light. An example of a longitudinal mechanical wave is a wave in water, while sound is an example of a compression wave.Full Answer >
