Web29 apr. 2016 · Energy emitted from a source is generally referred to as radiation. Examples include heat or light from the sun, microwaves from an oven, X rays from an X-ray tube and gamma rays from radioactive elements. Ionizing radiation can remove electrons from the atoms, i.e. it can ionize atoms. Web29 okt. 1996 · c = (1) where l is the wavelength of the wave, xx is its frequency, and c is the velocity of light. The spectrum of electromagnetic waves spans an immense range of frequencies, from near zero to more than 10 30 Hz (the Hertz, abbreviated Hz, is a unit of frequency. 1 Hz corresponds to 1 cycle per second). A section of the electromagnetic …

Web3 feb. 2016 · Electromagnetic spectrum: ↑ The visible light that we can see is just a tiny part of the “electromagnetic spectrum.” Visible light is made of photons with medium energy. Photons with more energy are ultraviolet radiation, X-rays, and gamma rays (gamma rays have the most energy). WebElectromagnetism is one of the four fundamental forces of nature. The others are gravity, and the strong and weak interactions of particle physics. [1] The electromagnetic force pushes or pulls anything that has an electric charge, like electrons and protons. It includes the electric force, which pushes all charged particles, and the magnetic ... green hope ship
