Introduce the underlying scientific concepts that are essential to understanding how your gadget works.
Concept 1: Laser
a. Define the general term used scientists to identify the concept you are studying.
"LASER, acronym for light amplification by stimulated emission of radiation. Lasers are devices that amplify light and produce coherent light beams, ranging from infrared to ultraviolet. A light beam is coherent when its waves, or photons, propagate in step with one another. Laser light, therefore, can be made extremely intense, highly directional, and very pure in color (frequency). Laser devices now extend into the X-ray frequency range. Masers are similar devices for microwaves."
b. Additional terminology: What key terms that are used by scientists explaining this concept? Provide terms and definitions for each.
Atomic Emission- The emission of atomic line radiation may be described by an emission coefficient ε with units of energy/time/volume/solid angle.
Atomic Emission Spectrum- The atomic emission spectrum of an element is the set of frequencies of the electromagnetic waves emitted by atoms of that element. Each atom's atomic emission spectrum is unique and can be used to determine if that element is part of an unknown compound.
c. Diagrams and graphs you found that help explain this concept

Concept 2: Digital Information Process
a. Define the general term used scientists to identify the concept you are studying?
Digital Processing-" In digital technology, the analog wave is sampled at some interval, and then turned into numbers that are stored in the digital device."
b. Additional terminology: What key terms that are used by scientists explaining this concept? Provide terms and definitions for each.
Analog Wave-"In analog technology, a wave is recorded or used in its original form. So, for example, in an analog tape recorder, a signal is taken straight from the microphone and laid onto tape. The wave from the microphone is an analog wave, and therefore the wave on the tape is analog as well. That wave on the tape can be read, amplified and sent to a speaker to produce the sound."
