Define and discuss the following terms involving radiation: electric wave, magnetic wave, wavelength, wave amplitude, wave speed, black body, Stefan-Boltzmann law, Wien's law, electromagnetic bands

What will be an ideal response?


Answer: Electric wave: the electric component of an electromagnetic wave. magnetic wave: the magnetic component of an electromagnetic wave. wavelength: distance between wave crests. wave amplitude: the height of a wave. wave speed: the speed of light. black body: a hypothetical object that emits the maximum possible radiation at every wavelength. Stefan-Boltzmann law: the intensity of energy radiated by a blackbody increases according to the fourth power of its absolute temperature. Wien's law: hotter objects radiate energy at shorter wavelengths than do cooler bodies. electromagnetic bands: a grouping of wavelength rangesranges.
