Hi, What is the difference between Matter and Radiation?

Thank you all...:-)

Rain drop having free fall. Am I right..? That is it get accelarated. Means, velocity changing... But. Terminal velocity is a constat velocity. Then how it happens..?

Please, explain the concept of terminal velocity on the help of rain drops... Is there is any retardation when rain falling to the ground.?

Best... Wavelets are the second generation of waves coming from the first wave front(primary wave front)... This is according to Huygens wave theory. I think this is the reflection of a plane wave by a plane surface..

Actually,. What is optical equivalent path.,.? Is this and optical path length are same,.,.,??

Thaaanks...

Hi.. What will be the nature of relativistic mass when a body moves with speed of light..?

In circular motion why the centripetal and centrifugal not get cancelling. .?

Photons possesses mass, when it is moving., and rest mass of photon is 0...

In circular motion of any vehicles or any other particles, which experiences both centripetal and centrifugal forces... Why these two not cancelling?these are in equal and opposite.

Gamma decays are e.m.waves ..then how describe gamma decay in terms of energy levels?

Volt V is the unit of potential. Current means V/R i.e,voltage/resistance.

Thanks a lot...

From second law of motion, dP/dt propotional to F. i.e,m dV/dt propotional to F. To make this an equation,multiply with a constant. i.e,F=k m dV/dt. Where , k=1, then F=m dV/dt. We know that, dV/dt=a. There fore, F=ma.
