Uses, Hazards and Detecors of EM radiation Flashcards
What are the uses of radio waves?
Radio waves are used for broadcasting radio and TV signals, communications (e.g., mobile phones), and satellite transmissions.
What are the hazards of radio waves?
Radio waves generally have no significant hazards at common exposure levels.
What detectors are used for radio waves?
Aerials and radio receivers are used to detect radio waves.
What are the uses of microwaves?
Microwaves are used for cooking food, satellite communications, and mobile phone networks.
What are the hazards of microwaves?
Microwaves can cause internal heating of body tissues if exposed to high levels.
What detectors are used for microwaves?
Microwave receivers or special aerials detect microwaves.
What are the uses of infrared radiation?
Infrared radiation is used for remote controls, thermal imaging, and heating devices.
What are the hazards of infrared radiation?
Infrared radiation can cause skin burns if the exposure is high enough.
What detectors are used for infrared radiation?
Photodiodes, thermometers, and infrared cameras are used to detect infrared radiation.
What are the uses of visible light?
Visible light is used for illumination, photography, and vision.
What are the hazards of visible light?
Intense visible light can cause damage to the eyes, such as blindness.
What detectors are used for visible light?
Eyes, cameras, and photodiodes detect visible light.
What are the uses of ultraviolet radiation?
Ultraviolet (UV) radiation is used in fluorescent lamps, sterilization, and security marking.
What are the hazards of ultraviolet radiation?
Prolonged exposure to UV radiation can cause skin cancer and eye damage.
What detectors are used for ultraviolet radiation?
Fluorescent materials and UV photodiodes detect ultraviolet radiation.
