When electrons of high energy fall on metal X rays are produced.What about the metals having large atomic number and showing natural radio activity?Will there be a collision between the electrons and alpha and beta particle? I can not understand this. So please help me.
Though the intensity of violet light is more than that of blue we see the sky blue.Why this happens?Does it happen only for that our eyes are more sensible towards blue light than violet light or due to absorption of violet light by Ozone layer? And why different light waves having different...
I f a particle starts moving with the velocity of light it becomes massless.But practically a massless particle has no existence.Again one of the main constituents of light is photon,then is it a massless particle?But I know electron has the least mass in this world and photon is heavier than...
For an progressive wave why the phase particle lags behind of time than it's predecessor one ? we know for a particle which is at the origin follows the equation # # y=# # A sin \omega t...
