What are they?
- They're not hot enough to transmit visible light.
- The warmer the object, the more infrared waves that are transmitted.
- Between 7 nanometers and 1 mm
- Called thermography, used in in military and industrial settings.
Infrared Waves R Cool
- Dangerous to susceptible skin such as skin and eyes.
- The Green house effect, causes increased temperatures and changes in weather patterns that could be harmful to people and animals
- Infrared technology is employed in various devices, including night vision goggles, lasers, thermographic cameras, communications devices and weather satellites.
- Infrared rays help with the immune system by fighting viruses and bacteria
Tv remote - uses infrared energy to send signals from the remote to the tv that cannot be seen by the naked eye
Heating lamps - Special lamps that produce thermal infrared waves in fast food restaurants to keep food hot
About This Video
The electromagnetic spectrum contains many different types of waves, one of which is infrared waves. Other electromagnetic waves include gamma rays, x-rays, ultraviolet, visible light, microwaves, and radio. Infrared waves are electromagnetic radiation of a particular wavelength or color that we have named 'infrared.' They are between 700 nm and 1 mm. Infrared lights were discover by William Herschel around 1800. Infrared waves are used in many of our electronics such as TVs, blue ray players and commuters. Infrared waves can be used as night vision they are also used to study animals.
