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. When a light ray passes obliquely from air into water, it refracts away from the line perpendicular to the surface. Refraction of light makes a fish appear lower in the water than it really is.
