Odd Word/ Letter/ Number/ Number Pair
Explanation:
The given options are all types of electromagnetic waves. Electromagnetic waves are transverse waves that can travel through a vacuum and do not require a medium to propagate. They are characterized by their wavelength, frequency, and energy.
a) Ultraviolet: Ultraviolet waves have a shorter wavelength and higher frequency than visible light. They are used in various applications such as sterilization, fluorescence, and suntanning.
b) X-Rays: X-rays have an even shorter wavelength and higher frequency than ultraviolet waves. They are used in medical imaging, material analysis, and radiation therapy.
c) Infrared Rays: Infrared waves have a longer wavelength and lower frequency than visible light. They are used in heating, sensing, and communication applications.
d) Radio Waves: Radio waves have the longest wavelength and lowest frequency among the given options. They are used in broadcasting, communication, and navigation.
The odd word/letter/number/number pair is "D" Radio Waves because it has the longest wavelength and lowest frequency among the given options, while the other options have shorter wavelengths and higher frequencies.
Therefore, the correct answer is option 'D'.
