Final answer:
Combustion particles, ionization, and photoelectric effects are all related to smoke detectors, which use these principles to detect smoke and trigger alarms.
Step-by-step explanation:
Particles from combustion, ionization, and photoelectric effects are all used in smoke detectors. Smoke detectors are designed to sense particles or changes in the environment caused by smoke. There are two main types of smoke detectors: ionization smoke detectors and photoelectric smoke detectors. Ionization smoke detectors use americium-241 to ionize air and detect smoke particles disrupting the ion flow, which triggers the alarm. Photoelectric smoke detectors use a light beam that, if scattered by smoke particles, triggers the alarm. Both types are effective in detecting different kinds of smoke generated by various types of fires.
