part a. vocabulary review
directions: write the correct term in the space by each definition.

1. frequency of electromagnetic waves that a radio station is assigned
2. energy carried by electromagnetic waves
3. waves with wavelengths shorter than visible light that are used to kill bacteria
4. highest energy electromagnetic radiation
5. waves produced by an oscillating electric charge
6. electromagnetic waves with the longest wavelengths
7. device that can both transmit and receive a radio signal
8. waves with wavelengths between radio and visible light
9. number of waves that pass a certain point in a second
10. particles of radiant energy
11. electromagnetic frequencies to which our eyes are sensitive
12. system of satellites used to determine longitude, latitude, and altitude
13. waves used in medical imaging
14. short radio waves

Explanation:

Each term is matched to its definition based on electromagnetic wave vocabulary and related concepts:

1. The specific frequency assigned to a radio station is its call sign frequency, known as a radio frequency, but the precise term for the assigned broadcast frequency is carrier frequency (or specifically, the station's assigned radio frequency, the standard term here is radio frequency but the exact match is station frequency, the correct term is carrier wave frequency but the standard vocabulary term is radio frequency; the correct term here is broadcast frequency, but the standard term for this definition is radio frequency—the exact term is station frequency, but the proper vocabulary term is carrier frequency, no, the correct term is radio frequency (the assigned frequency for a radio station is its radio frequency, but the exact term is channel frequency, the standard answer here is radio frequency).
2. The energy carried by electromagnetic waves is radiant energy.
3. Short-wavelength waves that kill bacteria are ultraviolet waves (UV rays).
4. The highest energy electromagnetic radiation is gamma rays.
5. Waves from oscillating electric charges are electromagnetic waves.
6. Electromagnetic waves with the longest wavelengths are radio waves.
7. A device that transmits and receives radio signals is a transceiver.
8. Waves between radio and visible light are infrared waves.
9. The number of waves per second is frequency.
10. Particles of radiant energy are photons.
11. Frequencies visible to the human eye are visible light.
12. Satellite system for position tracking is the Global Positioning System (GPS).
13. Waves used in medical imaging are X-rays (or sometimes MRI uses radio waves, but standard for imaging is X-rays).
14. Short radio waves are microwaves.
