Answer:
Ultraviolet.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist. Also, it comprises of electric and magnetic field components.
An electromagnetic spectrum refers to a range of frequency and wavelength that an electromagnetic wave is distributed or extends. The electromagnetic spectrum comprises of gamma rays, visible light, ultraviolet radiation, x-rays, radio waves, and infrared radiation.
Radiation is simply the transmission or emission of energy in the form of particles or electromagnetic waves through a vacuum, material medium or space.
Basically, a type of electromagnetic radiation which is highest in energy is ultraviolet (UV) radiation. Although, ultraviolet (UV) radiation has a smaller wavelength.
