How do lasers use reflection for stronger beams?
Lasers use reflection by bouncing the light back and forth between mirrors placed at each end of a laser cavity. This allows the light to pass through the gain medium multiple times, amplifying the beam before it is emitted. This process results in a stronger and more focused laser beam.
How do you explain the characteristics of laser beam?
Laser beams are normally characterized as focused (the beam size enlarges slowly with distance), intense (don't look into a laser beam), and mono-energetic (single-color light). What is laser? -- laser stands for "light amplification by stimulated emission of radiation." What is being stimulated in laser? -- gas, solid-state, semiconductor, dye, chemical etc. Each type of laser has its own characteristics and pros and cons. The origin of laser radiation in a gas laser -- take a gas laser, for example. Argon gas is trapped inside a pressurized tube (low pressure to be exact). The tube's curved wall is coated with metal for reflection. Two flat mirrors are situated at each end of the long cylinder. Energy, in the order of kilowatts, is supplied to ionize the Argon gas. The excited Argon atoms will relax to release light in a very narrow spectrum, in the order of Watts -- very inefficient indeed. The mirrors and shiny curved wall are to keep the light generated to be trapped inside the tube intentionally, so that the lasing action can be amplified. The mirror at the "business" end has a small opening to allow light to escape. Hence the exiting laser beam is more or less uni-directional (focused). The light coming out of an Argon gas ranges from red to UV, but a filter at the exit can narrow the spectrum further to mono-chromatic. The filtered single-frequency light has little dispersion (photons will be traveling at about the same speed and few interference). The light is so intense and concentrated (~ 1 W over a beam size of 0.1 cm^2) that looking into a laser beam is detrimental to your eyes. Looking into a key-chain laser is not advisable either.

What produces a laser beam?
A simple and by no means comprehensive explaination is;A L.A.S.E.R (Light Amplification by Stimulated Emission of Radiation) is produced by 'pumping' energy into electromagnetic radiation, often light within a crystal or gas which has a mirror at one end and a semi-permeable mirror at the other. This energy aligns the light rays and gives them all the same frequency. They are then called 'coherent'. They bounce between the mirrors until such an energy lever is acheived whereby the beam breaks out of the semi mirror in a tight powerful beam.
What is the name of the top plates on a balance beam?
The top plates on a balance beam are called end plates. They are typically located at the ends of the beam and are used to stabilize and secure the beam in place during use.
Condition that will increase the moment in beam?
Increasing the force applied to the beam or increasing the distance from the force to the point of interest on the beam will increase the moment in the beam. Additionally, changing the angle of the force relative to the beam will also affect the moment.
How do you get passed the laser beam in the BAD control center?
You cant. But maybe at the end.
What is finite sets?
A finite set is a set that has numbers you can count. Its not like infinite with no end it has an end.
What is finite sequence?
Has an end.
What is spiking in ruby laser?
In a ruby laser, spiking refers to the phenomenon where there are short but intense bursts of laser light emitted between the main laser pulses. This can happen due to the presence of residual optical feedback or internal reflections within the laser cavity, causing these uncontrolled spikes in laser output.
What is the difference between an infinite sequence and a finite sequence?
A finite sequence has a beginning and an end, whereas an infinite sequence has no end.

What does finite or infinite mean?
finite means something will come to an end in a certain time. infinite means it has no end i.e. keeps going
What is finite and infinite set?
A set which containing $and pi are the end blocks are the finite and without these are infinite
What does finite or infinite mean in maths?
infinite means never ending whilst finite means it has a end
When did Laser Broadcasting end?
Laser Broadcasting ended in 2009.

How do you use finite resources well?
You don't. End of.
