when an electron drops from a higher energy state to a lower it emits a fixed frequency photon
Gallium Arsenic Silicon Carbon have bright lines in a band of infrared can be varied colors depending on proportions
this is monochromatic IR
if you put parallel mirrors on either side of the the activated atoms you get a laser
co2 gas laser ... Led Solid laser
although IR is produced by burning sugar in a body and digital cameras can see that too
What else can I help you with?
How positive rays are produced in a discharge tube?
deflected away from a negative plat
Is there uranium in X-ray machines?
No, X rays are EM radiation and are produced by electrical/electronic equipment
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
Cathode rays were shown to be a stream of?
Cathode rays are electrons.
What are the rays in the cathode ray tubepositive or negative or neutral?
The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.
Which rays are used in burglar alarm?
Ultraviolet rays
Is a gamma ray a transmitter?
yes it can be used as a transmitter as well because few t.v. remotes used to have very light gamma rays to command t.v. sets but gamma rays are dangerous as they can cause cancerANS2:No, there is no such thing as a gamma wave transmitter. That implies that a man-made device is producing the radiation. In the case where electromagnetic waves of the same wavelength as gamma are produced artificially, those waves are called x-rays. Yes, there are x-ray transmitters. Gamma radiation is produced from natural processesX-rays are (usually) artificially produced gamma radiationAs for gamma ray t.v. remotes: the radiation used for the signal is way less energetic than gamma...less energetic than visible light. They all use infra red.
What are the 4 radioactive rays produced?
You think probable to beta rays, gamma rays, alpha rays.
What are the rays that are produced by the sunlight?
Rays that come from the sun are Ultraviolet rays (UV). You also get light rays and heat waves.
How is ultraviolet produced?
The sun's rays
Are Thermograms are produced by X-rays?
Nope.
Why infra red rays are used mostly in security alarm?
simple its cheap and works
What is solar enerergy?
It is energy produced by the sun's rays.
Do x rays have higher energy than gamma rays and why?
No, gamma rays have higher energy than X-rays. Gamma rays have shorter wavelengths and higher frequencies than X-rays, making them more energetic. Gamma rays are produced by the decay of atomic nuclei or during nuclear reactions, while X-rays are produced by accelerating charged particles or through atomic transitions.
What are some examples or infrared rays?
A remote control,alarm systems,heat lamps, and satellites.
Which layer of the sun are gamma rays photons produced?
The core
What is another name for x-rays?
Röntgen rays, actinism, cathode rays,encephalogram, fluoroscope, radioactivity,radiograph, refractometry,
