If the electric field in an electromagnetic wave is increasing in magnitude at a particular time, is the magnitude of the magnetic field at the same time increasing or decreasing? Explain.
Chapter 4: Energy and Heat 02/13/2017 ▯ Radiation o All objects emit electromagnetic radiation just because they have a temperature. This is a type of energy transfer by heat. o Rate at which energy is emitted increases with temperature (hotter objects emit more radiation). o The type of radiation given off also depends on temperature. Type depends on the frequency of the electromagnetic wave. Hotter objects emit radiation with higher frequencies (and therefore smaller wavelengths). Examples: visible, infrared, ultraviolet, etc. ▯ ▯ Electromagnetic Radiation o Electromagnetic radiation: energy carried as electromagnetic waves. o Waves h
