Nope.The Speed Of Light Now Known Is The Fastest.Because, If A Particle ( Eg.Photon) Moves At The Speed Of Light ( i.e The Speed Of Light In Vaccum(299 792 458 m/s), Its Mass Would Be Zero . So Is There Anything With A Mass Of Value With A Negative Sign (eg.-12kg)?So The Speed Of Light Now Known...

1.how to derive the Planck's constant ? how does he found that?how can it be correct? 2.derivation of E=mc^2.

1.what is lorentz transformations ? what are the uses of it ? 2.there are 2 galilean transformations equations .what are the uses of them ? are they useful to find the velocity of the objects at different reference frames or they have anyother applications/uses?

1.photon has no mass . so m=0.hence, p=mv=0.by doing some calculations , we can get that p=h/lambda.we can prove p=mv experimentally.but how can we prove the second one experimentally?

1.how and why does a light source in an isotropic medium at INFINITY produces PLANE Wavefronts instead of CIRCULAR Wavefronts as in case , when a light source is in the same isotropic medium but at FINITE distance? 2.how and why does a linear source of light such as a slit illuminated ...

plane and solid angles are collectively called as supplementary quantities.it's a bit confusing . it is better if there is any animated video. :)

Confusing Solid And Plane Angles ! Supplementary Quantities - 1.Solid Angle - Steradian 2.Plane Angle - Radian Doubts - 1.What Is The Use Of Supplementary Quantities ? Physical Quantities Are Used To Measure For Example .. To Measure Length - m Current - ampere Etc... What Can I...

Thanks Alot Thanks Alot For Your Help :) I Have Another Doubt . Does It Mean The Radius or Diameter ? Because Wavelength Of Gamma Rays is 10(power -15) which is the diameter of nucleus .so you're referring to diameter ... (right?)

I Watched A Video . In Which , It's Mentioned That The Relative Size Of.. Gamma Rays - Atomic Nucleus X-Rays - Atom Ultra-Violet Rays - DNA Visible Light - Bacteria ... Radio Waves - Mountain Ranges What's Mean By Relative Size ? I'm Confused Alot ! Thanks Alot In Advance For...

the first link is very helpful :) what is the second link for ? i will read the details in first link in coming saturday and reply you :) thanksssss a lot ;)

Thanks Alot :) sure .. rutherford used radium which emitted the alpha particles ( right ? ) . then , how does the alpha particles emitted ? does they emitted by radioactivity ( alpha-decay) ? thanks in advance :)

everyone of us know that rutherford gave his own atomic model from the results of gold foil scattering experiment. my doubt is , 1.how was he able to see the alpha particles deflected ? (important doubt ) 2.does alpha-decay happened to emit alpha particles in the radium he took ?

Thanks Thanks Alot Everyone.I'm Asking Doubts Here As I Want To Learn Everything From Basic.So I Will Be Clear In All The Ways. My School Has Started Again , The Leave Is Over . I Don't Have Much Time To Read Online. If I Get Time , I Will Ask Here :) Thanks Alot Again..... ( I Must Schedule...

Thanks You , Sir :) 1.What is cross section ? 2.why can't we use anyother elements other than uranium such as helium , aluminium , silver ? will they absorb neutrons without fissioning? 3.can human able to do nuclear fusion in Earth ? if yes , say how . if no , why? 4. i want to a lot of...

i know few things about nuclear reactors .i have a lot of doubts.i want to know everything completely such as 1.how control rods absorb neutrons? 2.how do scientists know what's happening inside an atom? and so on.... " can anyone tell me the complete details about nuclear reactors ? "...
