Answer:
1. C
Frequency refers to the number of occurrences of a periodic event per time and is measured in cycles/second. In this case, there is 1 cycle per 2 seconds. So the frequency is 1 cycles/2 s = 0.5 Hz.
2. D
Radiation causes cancer, cellular damage, and death but not viral infection since you only get it when a virus enters your body through inhalation, ingestion, bites and many other ways.
3. C
Electromagnetic waves vary in wavelength and freqeuncy. Longer wavelength electromagnetic waves have lower frequency and shorter wavelength.
4. A
5. C
The electromagnetic (EM) spectrum is the range of all types of EM radiation. The other types of EM radiation that make up the electromagnetic spectrum are microwaves, infrared light, ultraviolet light, X-rays and gamma-rays.
