NDCR

This is for my electronics and physics friends,
I developed a small tool for calculating resistor values either by giving values through color or based on bands.
Iam trying to improve this tool with your valuable feedback.

NDCR : New Dimension of Calculating Resistors.

Pre-requirements:

1. Browser (eg:- Internet Explorer or Firefox).
2. JRE. (Java Runtime Environment).

Already many tools are available for calculating resistor values but this tool is my contribution.

If you don't have JRE installed in your machine, please download it.

LIGHT

 LIGHT

Some body think light is a simple concept. what  special in this?

But all can't know this.

In this article i will explain very simply like to teach to child's.

Lets come to the concept. Photon is the quantum particle of light. Quantum particle means very smallest particle.

Naturally Photon in wave nature. 

Where is the Light come from?

How it can travel at high speed?

I will explain it detailly. Light is emitted from the electron. How?

In normal condition it will not emit anything. if we applied some energy means it will emit.

we all know in an atom electron revolve the nucleus. If we apply energy to the valence electron(electron's in last orbit) it jump from lower energy state to higher energy state.

Whats is lower energy state and higher energy state?

Normally every orbit has its own energy. In the last orbit also has some energy but low as compare to first orbit. So we need to apply only less amount of energy to jump electron to higher energy state and as quickly it returns to original position. When it return to original position it emits the supplied energy.

 Now i hope you clear about how energy is transferring from electron.
Electron emits that energy in terms of photon. i already told combination of photon is a light.

then You have another question.

All the atoms has electrons then why light doesn't emit from that atoms like copper, zinc, etc.?
Why it emits only from some kind atoms like sodium, tungsten, etc.?

 That's the good question.

What i told is right. All the atoms are emitting  photons. But we can't see.Why?

Light depends on Energy of emitted photon. For each and every atom has different no.of electrons and different energies. So depends on that i will emits the photons.

I think  you confused.

If we applied the force on the atom the electron goes to higher energy states. then it emits photon.
for example

daily in our life We are using tungsten lamp. In that when we switch ON suddenly it doesnt emit photon. Initially it get heated. Initially thats mean applied energy(electric power) is low so it getting heat if we applying energy continuously it getting more heated and goes to reddish color. if the applied energy goes over the limits means after wards only electrons starts to emit photon(like visible light).

Before electron emit photon in visible range. it emits photon but with lower energy so cant see that it is in like infrared light spectrum. 


All the atoms are emitting photons but depend on the energy light is produced in different range.


if we applied more amount of energy means electrons jumps to very higher energy states and it gets more vibrating so the frequency of emitted photon also high. According to the electromagnetic spectrum we can find which type of light range in emitted from the electron.


Now i hope all are clear about the concept of LIGHT.

Einstein Energy Equation

EINSTEIN ENERGY EQUATION

we all know, Einstein energy equation is very popular and apply for all extreme.

Some of them knows about that equation but what's the real concept behind.

now i will explain briefly about energy equation E=MC^2.

we all know,
E = ENERGY
M = MASS
C = SPEED OF LIGHT.

what's the main concept of this equation is to find the energy of an object or mass?

definition of this equation is :

"multiply the mass of the object by twice the time of speed of light."

speed of light is approximately 3*10^8.

why Einstein take these quantities to find the energy of an equation?

this is the main part of this article. watch carefully


what i researched about this concept is :


if we want to the find energy of an mass means first we need to know energy of an single electron. then only we can find energy for whole mass.

why we need to find energy for single electrons means, atom is the very very small particle in the mass. so if we find the energy of a small mass means we can multiply to mass of an object.

now you have one question,
why einstein take the speed of light in the energy equation?
its the good question. here only the einstein proves his stuff.

why he take speed of light means?

we all know in our knowledge light only can travel maximum speed in the universe.
if a particle can travel at high speed means it has large amount of energy.

i think you confused in this matter.
lets i explain with an example.

you can take our body as an example. if we have lot of energy means we can do lot of works and less amount energy means we can't do much works. our body also depends on energy. if you confused means take a ball it can travel at the speed depends on force we applied and energy in the ball. if we applied more force, energy of an ball is low means it will damage else it travel at high speed.

Now we all clear on if a object travel at a speed depends on the energy of the object.

By this concept only einstein found energy of a single electron. how?

we all know light is emitted from the electron, i already said if a object has more energy means it can do more works. if light can travel at very high speed means electron has large amount of energy. energy of an electron is directly proportional to the speed of the light.

we know speed of light so easily we can find out the energy of a single electron. then multiply the speed of light to the mass of the object. why we want to multiply means we only found the energy of single atom so we need to find energy of whole mass.

Then you can have another question why einstein multiply twice the speed of light?

this question is raise for me also, then only studied if we focused to a single electron, it will emit twice photon.

that means exciting wavelength is shorter than the emission wavelength.


so now i believe you all clear about the concept of energy equation.

thank you for all visiting this article.
