The wavelength of light emitted from a distance object is related to ________.
◦ the energy of the source. A more energetic source has lower wavelength emissions
◦ distance of the source–the farther away the object is, the lower the wavelength observed related to changes in electromagnetic energy over time
◦ the energy of the source. A more energetic source has higher wavelength emissions
◦ gravity–gravity bends electromagnetic waves causing refraction and sorting of wavelengths
