ENERGIES OF PHOTONS Flashcards
is the whole range of the electromagnetic waves that are present and acknowledged in the entire cosmos.
ELECTROMAGNETIC SPECTRUM
the frequency of a wave is directly proportional to its energy. So, the higher the frequency, the higher the energy the wave carries.
true or false
true
applied to AM and FM radio stations, old TV broadcasting, submarine communications, mines, and old-school mobile phones.
Radio waves
are utilized in ovens, TV satellites, old-school long–distance telephone transmission, and RADAR systems for identifying displacements of particular terrains, aircraft, and the like.
Microwaves
are used in war to detect enemies at nighttime, thermal motion imaging in airports, security systems, short-range controllers, and thermal scanners.
Infrared waves
is the safest electromagnetic spectrum that humans can get in contact with now and then. Generally, it serves essential purposes to humans and other living entities.
Visible light
are found in special lamps for forensic investigation, fluorescent lamps, devicen that authenticate banknotes and currency, pest control devices, equipment that sterilize medical tools, and sunlight that can cause sunburns and calcium retention.
Ultraviolet waves
are used in x-ray vision of soft and hard tissues of the human body, on TV broadcasts, and even in computers but the amount of energy is deregulated to make them safe for humans.
X-rays
are employed in sterilizing medical equipment, killing bacteria and viruses that cause foodborne-related diseases, radiation therapy, and gamma knife surgery.
Gamma rays
is something visible to the human eyes produced due to certain energy that photons of light carry.
Color
Red light must be used in order to preserve the quality of the photographs developed in a traditional way.
PHOTOGRAPHIC DARKROOM
—– has the least frequency and so does the weak energy. Therefore, the —– cannot produce fogging and blurring in the photo papers.
Red light
People get —— when they do not have the right protection on their skin. Ultraviolet rays are ones of the many electromagnetic spectrum released by the sunlight aside from infrared and visible light.
SUNBURN
