Document Summary
The higher the frequency, the higher the energy. They are directly proportional (as one increases, so does the other) They are caused by the movement of electrons or a change in the magnetic field. Electrons moving around causing disturbances in the. All the parts of the spectrum except visible light. Gamma rays, x-rays, uv rays, infrared waves, microwaves, radiowaves. Colours are just different wavelengths of the emspectrum. If you do not blue light on that shirt, it won"t reflect any blue light back and it won"t appear blue. An object that absorbs all the wavelengths of light appears to be black. We have an object here, the white light is coming and hitting this object, it absorbs all the white light until we don"t see anything, black colours is the absence of light. The material is absorbing all the wavelengths of visible light and it"s not reflecting anything back so it"s black in colour.
