What kind of energy produces light?

Answer 1

Energy is inversely proportional to wavelength, and depending on the wavelength specified, various types of energy from radio waves to gamma rays can be produced, gamma rays being of the highest energy and the shortest wavelength.

Answer 2

Electromagnetic waves can be described by their wavelengths, energy, and frequency. All three of these things describe a different property of light, yet they 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.

In fact, X-rays and gamma-rays are usually described in terms of energy, optical and infrared light in terms of wavelength, and radio in terms of frequency. This is a scientific convention that allows the use of the units that are the most convenient for describing whatever energy of light you are looking at. After all - there is a huge difference in energy between radio waves and gamma-rays. Here's an example. Electron-volts, or eV, are a unit of energy often used to describe light in astronomy. A radio wave can have an energy of around 4 x 10-10 eV - a gamma-ray can have an energy of 4 x 109eV. That's an energy difference of 1019 (or ten million trillion) eV!

Answer 3

Energy is inversely proportional to wavelength: the shorter the wavelength (X-rays, gamma rays) the greater the energy.

Answer 4

Electromagnetic Waves don't produce energy, they carry it. A photon's energy is given by E=hf, with h= planck's constant and f= frequency.

Answer 5

electromagnetic energy produces light.

Answer 6

Shorter = more energy
