The simplest electron orbital is pictured in our text as a spherical shell. None of these. An orbital is the path a planetary electron follows as it moves around the nucleus of an atom. The following questions have a single correct answer 20. Radio waves have longer wavelengths than gamma rays.
Infrared rays have higher frequencies than X-rays.
Gamma rays have longer wavelengths than ultraviolet rays. Blue light has a longer wavelength than green light. The wavelength range of visible light is 20-20,000 Angstroms. The speed of electromagnetic waves through free space depends on their frequency. The wavelength of visible red light is about 400 nanometers.
