Detailed Solution

The amount of refraction increases as the wavelength of light decreases. Shorter wavelengths of light (violet and blue) are slowed more and consequently experience more bending than do the longer wavelengths (orange and red).

Visible light is just one of many types of electromagnetic radiation, and occupies a very small range of the overall electromagnetic spectrum. Hence R is false.
