If you start at violet and go higher in frequency and shorter in wavelength, you get ultraviolet radiation.

If you start at violet and go higher in frequency and shorter in wavelength, you get ultraviolet radiation.

• A. Infrared
• B. Ultraviolet radiation
• C. Microwave
• D. X-rays

Answer: (B)

Light behaves in a way where wavelength and frequency are inversely related: shorter wavelength means higher frequency because c = fλ. Violet light sits at the short-wavelength end of the visible spectrum, so moving to even higher frequency and shorter wavelength takes you into ultraviolet radiation, which lies just beyond violet. Infrared and microwaves have longer wavelengths (lower frequencies) than visible light, while X-rays have shorter wavelengths than ultraviolet, placing them beyond ultraviolet in the spectrum.
