Roland · Answer 1

Waves that have longer wavelengths and higher frequencies

Answer: Option A.

Explanation:

Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light-is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400.

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.
