Electromagnetic Waves Report Error. D Microwaves. Solution: Here microwave. Questions from Electromagnetic Waves. A plane electromagnetic wave travels in vacuum along z-direction. An electric charge in uniform motion produces. Electromagnetic waves are produced by. Different types of light tell us different things.

See interactive examples. Radio waves and microwaves, which have the lowest energies, allow scientists to pierce dense, interstellar clouds to see the motion of cold gas. Infrared light is used to see through cold dust; study warm gas and dust, and relatively cool stars; and detect molecules in the atmospheres of planets and stars. Most stars emit the bulk of their electromagnetic energy as visible light, that sliver of the spectrum our eyes can see.

Hotter stars emit higher energy light, so the color of the star indicates how hot it is. This means that red stars are cool, while blue stars are hot. Beyond violet lies ultraviolet UV light, whose energies are too high for human eyes to see.

UV light traces the hot glow of stellar nurseries and is used to identify the hottest, most energetic stars. X-rays come from the hottest gas that contains atoms. They are emitted from superheated material spiraling around a black hole, seething neutron stars, or clouds of gas heated to millions of degrees.

Gamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum. They come from free electrons and stripped atomic nuclei accelerated by powerful magnetic fields in exploding stars, colliding neutron stars, and supermassive black holes.

More to Light than Meets the Eye. The electromagnetic spectrum consists of much more than visible light. What Is the Electromagnetic Spectrum? How We Measure Light Light travels in waves, much like the waves you find in the ocean. Comparison of different types of light, including wavelength size, and frequency. All three of these things are related to each other mathematically. This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave.

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
