Question

practice 5: match each type of electromagnetic radiation with the most appropriate application
a. high - energy ultraviolet light waves
b. long - wavelength, ultra - low frequencies
c. infrared radiation
d. radio waves

1. sterilization of medical environments
2. communication with underground or undersea vehicles
3. heat - sensing cameras
4. \over - the - air\ communications

Explanation:

1. High - energy ultraviolet light waves (\(UV - C\) specifically) can kill bacteria and viruses, so they are used for sterilization of medical environments.
2. Long - wavelength, ultra - low frequencies can penetrate through water and soil better than other electromagnetic waves, making them suitable for communication with underground or undersea vehicles.
3. Infrared radiation is related to heat. Heat - sensing cameras detect infrared radiation emitted by objects based on their temperature.
4. Radio waves are commonly used for "over - the - air" communications such as in television, radio, and mobile phone signals.

Answer:

1. A. High - energy ultraviolet light waves
2. B. Long - wavelength, ultra - low frequencies
3. C. Infrared radiation
4. D. Radio waves
