Electromagnetic Spectrum: Radio Waves
Science & Reason on Facebook: tinyurl.com Science@NASA: EMS Electromagnetic Spectrum (Episode 2) - Radio Waves The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object is the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. --- Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com • www.YouTube.com • www.YouTube.com --- MEASURING THE ELECTROMAGNETIC SPECTRUM The electromagnetic (EM) spectrum is just a name that scientists give a bunch of types of radiation when they want to talk about them as a group. Radiation is energy that travels and spreads out as it goes - visible light that comes from a lamp in your house and radio waves that come from a radio station are two types of electromagnetic radiation. Other examples of EM radiation are microwaves, infrared and ultraviolet light, X-rays and gamma-rays. Hotter, more energetic objects and events create higher energy radiation than cool objects. Only extremely hot objects or particles moving at very high velocities can create high-energy radiation like X-rays and gamma-rays. • imagine.gsfc.nasa.gov --- RADIO WAVES Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. Like all other electromagnetic waves, they travel at the speed of light. Naturally-occurring radio waves are made by lightning, or by ...

What is radio wave and how is radio wave produced?
Electric current creates magnetic field and oscillating electric current creates oscillating magnetic field and NOT electromagnetic wave Maxwells electromagnetic wave theory of light originated mostly from three phenomenons. 1) When a conductor oscillates in a magnetic field, oscillating electricity is created within the conductor. 2) Electric current creates magnetic field around a conductor. 3) Faraday effect: - the rotation of the plane of polarization of light by the application of a magnetic field. Maxwell has mistakenly concluded that, if an oscillating magnetic field creates an oscillating electric field in a conductor, an oscillating magnetic field should also create oscillating electric field in empty space. He has also believed that, oscillating electric field in space creates oscillating magnetic field. These beliefs have led him to develop his electromagnetic wave theory of light. The theory says that, light is an electromagnetic phenomenon and the perpendicularly oscillating electric and magnetic fields in space makes the propagation of light. In this presentation, we can see that, an oscillating magnetic field can create an oscillating electric field only in a conductor and not in empty space. When a conductor breaks a magnetic field, the magnetic field lines exert force on the free electrons in the conductor and which causes an unbalanced charges between the ends of the conductor (accumulation of electrons in one direction). But if the conductor oscillates ...
